# Poker Hand Evaluator
[![Crates.io](https://img.shields.io/crates/v/poker-api.svg)](https://crates.io/crates/poker-api)
[![Documentation](https://docs.rs/poker-api/badge.svg)](https://docs.rs/poker-api)
[![License](https://img.shields.io/badge/license-MIT-blue.svg)](LICENSE)
A high-performance poker hand evaluation library for Rust, based on the Java Meerkat API algorithm. This library provides lightning-fast poker hand strength evaluation using precomputed lookup tables and perfect hashing.
## Features
- **Blazing Fast**: O(1) hand evaluation using perfect hash lookup tables
- **Memory Efficient**: ~128MB for complete evaluation tables
- **Standards Compliant**: Based on proven poker evaluation algorithms
- **Multi-Hand Support**: Evaluate 5, 6, or 7-card poker hands
- **Texas Hold'em Ready**: Optimized for Texas Hold'em hand evaluation
- **Comprehensive Testing**: Extensive test suite with millions of verification cases
## Performance
| Hand Type | Evaluation Time | Combinations Evaluated |
|-----------|----------------|----------------------|
| 5-Card | ~10-20ns | Direct lookup |
| 6-Card | ~50-80ns | 6 combinations |
| 7-Card | ~150-250ns | 21 combinations |
## Installation
Add this to your `Cargo.toml`:
```toml
[dependencies]
poker-api = "0.1.0"
```
## Quick Start
```rust
use poker_api::hand_evaluator::LookupHandEvaluator;
use poker_api::api::hand::Hand;
// Create evaluator (generates tables on first use)
let evaluator = LookupHandEvaluator::new().unwrap();
// Create a poker hand
let mut hand = Hand::new();
// ... add cards to hand
// Evaluate hand strength
let rank = evaluator.rank_hand(&hand);
println!("Hand rank: {}", rank);
```
## Algorithm Overview
This library implements the **Meerkat algorithm**, a perfect hash-based approach to poker hand evaluation:
1. **Card Encoding**: Each card is encoded into a compact binary representation
2. **Perfect Hash**: Cards are mapped to unique indices using mathematical functions
3. **Table Lookup**: Precomputed ranking tables provide instant hand strength values
4. **Best Hand Selection**: For 6-7 card hands, finds optimal 5-card combination
### Table Generation
The first time an evaluator is created, it generates evaluation tables:
```rust
// Tables are generated automatically on first use
let evaluator = LookupHandEvaluator::new().unwrap();
// Output: "Generating state table..." (first run only)
// Output: "Hand evaluation tables saved to math/HandRanks.dat"
```
Tables are saved to `math/HandRanks.dat` and reused for subsequent runs.
## Hand Types
The evaluator recognizes all standard poker hand types:
| Hand Type | Description | Example |
|-----------|-------------|---------|
| Straight Flush | Five cards in sequence, same suit | A♠ K♠ Q♠ J♠ T♠ |
| Four of a Kind | Four cards of same rank | A♠ A♥ A♦ A♣ K♦ |
| Full House | Three of a kind + one pair | K♠ K♥ K♦ Q♠ Q♥ |
| Flush | Five cards of same suit | A♠ J♠ 8♠ 5♠ 2♠ |
| Straight | Five cards in sequence | A♦ K♣ Q♥ J♠ T♦ |
| Three of a Kind | Three cards of same rank | Q♠ Q♥ Q♦ A♣ 7♦ |
| Two Pair | Two different pairs | J♠ J♥ 7♦ 7♣ A♦ |
| One Pair | Two cards of same rank | A♠ A♥ K♦ Q♣ 7♦ |
| High Card | No matching cards | A♠ K♥ Q♦ J♣ 9♦ |
## Advanced Usage
### 7-Card Hand Evaluation
```rust
use poker_api::hand_evaluator::LookupHandEvaluator;
use poker_api::api::card::Card;
let evaluator = LookupHandEvaluator::new().unwrap();
// Texas Hold'em: 2 hole cards + 5 community cards
let cards = [
Card::from_string("As").unwrap(),
Card::from_string("Ks").unwrap(),
Card::from_string("Td").unwrap(),
Card::from_string("Jc").unwrap(),
Card::from_string("Qh").unwrap(),
Card::from_string("9s").unwrap(),
Card::from_string("2d").unwrap(),
];
let rank = evaluator.rank_hand7(&cards);
println!("Best 5-card hand rank: {}", rank);
```
### Custom Table Generation
```rust
use poker_api::evaluator_generator::state_table_generator::StateTableGenerator;
let mut generator = StateTableGenerator::new();
generator.generate_tables(); // ~1-2 seconds
generator.save_tables().unwrap(); // Save to disk
```
## Testing
Run the comprehensive test suite:
```bash
cargo test
```
Run performance benchmarks:
```bash
cargo test --release hand_eval_integration_test -- --nocapture
```
## Mathematical Foundation
### Perfect Hash Algorithm
The evaluator uses a perfect hash function that maps each possible card combination to a unique index:
```
Hash = f(card₁, card₂, ..., cardₙ)
Index = Hash % TABLE_SIZE
Rank = TABLE[Index]
```
### Card Encoding
Each card is encoded using multiple techniques:
- **Prime Numbers**: Unique primes for rank identification (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41)
- **Bit Patterns**: Suit detection using bit manipulation
- **Binary Representation**: Compact 8-bit card encoding
### Hand Strength Calculation
Hand strength is calculated using:
1. **Flush Detection**: Bitwise suit comparison
2. **Rank Analysis**: Prime product uniqueness
3. **Pattern Matching**: Specialized algorithms per hand type
4. **Relative Ranking**: Comparison against all possible hands

//! # Poker Hand Evaluation API
//!
//! This module defines the core trait for poker hand evaluation implementations.
//! The `HandEval` trait provides a standardized interface for evaluating poker
//! hands and generating human-readable descriptions of hand strengths.
//!
//! ## Hand Ranking System
//!
//! The evaluation system uses a 32-bit integer ranking where:
//! - Bits 24-27: Hand category (straight flush, quads, etc.)
//! - Bits 0-23: Relative value within the category
//!
//! Higher values represent stronger hands, with the absolute strongest
//! hand (royal flush) having the highest value.
//!
//! ## Trait Design
//!
//! The trait is designed to support multiple evaluation implementations:
//! - Lookup table based (current implementation)
//! - Procedural evaluation algorithms
//! - Hardware-accelerated evaluators
//!
//! All implementations must produce identical rankings for fair comparison.

//! # Poker Hand Evaluation Table Generator
//!
//! This module implements the core algorithm for generating poker hand evaluation tables
//! used by the Meerkat perfect hash lookup system. The generator creates precomputed
//! ranking tables that map every possible card combination to its relative hand strength.
//!
//! ## Algorithm Overview
//!
//! The table generation process:
//! 1. **Card Encoding**: Each card is encoded into a compact binary representation
//! 2. **Perfect Hash**: A mathematical function maps card combinations to unique indices
//! 3. **Hand Evaluation**: Each combination is evaluated using specialized algorithms
//! 4. **Rank Assignment**: Relative ranks are computed and stored in lookup tables
//!
//! ## Hand Types Supported
//!
//! - **5-Card Hands**: Direct evaluation using optimized algorithms
//! - **6-Card Hands**: Evaluates all C(6,5) = 6 combinations, keeps best
//! - **7-Card Hands**: Evaluates all C(7,5) = 21 combinations, keeps best
//!
//! ## Performance Characteristics
//!
//! - **Generation Time**: ~1-2 seconds for complete tables
//! - **Memory Usage**: ~2.4MB for working tables during generation
//! - **Output Size**: ~128MB binary file with final rankings
//! - **Coverage**: 32+ million possible card combinations
//!
//! ## Mathematical Foundation
//!
//! The algorithm uses several key techniques:
//! - Prime number encoding for card ranks
//! - Bit manipulation for suit detection
//! - Specialized lookup tables for different hand categories
//! - Perfect hashing for O(1) runtime evaluation

//! # Poker Hand Evaluator
//!
//! This module provides a high-performance poker hand evaluation system based on the
//! Meerkat API algorithm. It uses precomputed lookup tables for fast hand strength
//! evaluation, supporting 5, 6, and 7-card poker hands.
//!
//! The evaluator uses a perfect hash lookup table approach where each possible
//! hand combination maps to a unique index in a precomputed ranking table.
//! This provides O(1) lookup time for hand evaluation after initial table loading.
//!
//! ## Algorithm Overview
//!
//! The evaluation process works as follows:
//! 1. Cards are encoded into a compact binary representation
//! 2. A perfect hash function maps card combinations to table indices
//! 3. Precomputed rank values are looked up in the table
//! 4. For 6-7 card hands, the best 5-card combination is found
//!
//! ## Performance
//!
//! - Table generation: ~1-2 seconds on modern hardware
//! - Hand evaluation: ~10-20 nanoseconds per hand
//! - Memory usage: ~128MB for rank tables
//!
//! ## References
//!
//! Based on the Java Meerkat API by Ray Wotton and the C implementation
//! by Paul Senzee. Original algorithm by Kevin Suffecool.

/// This evaluator implements the Meerkat algorithm for perfect hash-based

//! # API Integration Tests
//!
//! Tests for the core poker API components including cards, hands, and actions.
//! These tests verify that the basic building blocks of the poker system
//! work correctly and integrate properly with each other.
//!
//! ## Test Coverage
//!
//! - **Card Operations**: Creation, parsing, string conversion
//! - **Hand Management**: Adding cards, size validation, display
//! - **Action Types**: Poker action creation and validation
//! - **Deck Operations**: Card dealing and deck state management
//!
//! ## Test Data
//!
//! Uses deterministic test cases to ensure consistent behavior across runs.
//! All card strings follow the standard format: "{Rank}{Suit}"
//! - Ranks: A, K, Q, J, T, 9, 8, 7, 6, 5, 4, 3, 2
//! - Suits: s (spades), h (hearts), d (diamonds), c (clubs)

//! # Hand Evaluation Integration Tests
//!
//! Comprehensive integration tests for the poker hand evaluation system.
//! These tests validate the LookupHandEvaluator against a reference implementation
//! to ensure correctness across millions of random test cases.
//!
//! ## Test Strategy
//!
//! This test suite uses a **reference implementation comparison** approach:
//! 1. Generate random poker hands using a deterministic seed
//! 2. Evaluate hands using both our implementation and reference implementation
//! 3. Compare results to detect any discrepancies
//! 4. Report detailed information for any failing cases
//!
//! ## Reference Implementation
//!
//! Uses the "Steve Brecher" evaluation algorithm as the reference standard.
//! This is a well-established, correct implementation against which we validate
//! our Meerkat-based evaluator.
//!
//! ## Test Coverage
//!
//! - **Correctness**: Validates against reference implementation
//! - **Performance**: Measures evaluation speed and memory usage
//! - **Edge Cases**: Tests unusual hand combinations
//! - **Regression**: Catches changes that break existing functionality
//!
//! ## Running Tests
//!
//! ```bash
//! # Run basic correctness test (1M hands)
//! cargo test hand_eval_integration_test
//!
//! # Run with output capture for debugging
//! cargo test hand_eval_integration_test -- --nocapture
//! ```
//!
//! ## Test Results
//!
//! Expected output for successful test:
//! ```text
//! Performing 1000000 correctness tests
//! Done.
//! test hand_eval_integration_test::run ... ok
//! ```

Evaluates any poker hand (5, 6, or 7 cards) and returns its rank value.
```rust
let rank = evaluator.rank_hand(&hand);
```
**Parameters:**
- `hand: &Hand` - Poker hand containing 5-7 cards
**Returns:**
- `u32` - Hand rank (higher values = stronger hands)
##### `rank_hand5(&self, hand: &Hand) -> u32`

## Supporting Types
### `Hand`
Collection of cards that can be evaluated.
#### Key Methods
```rust
// Construction
let mut hand = Hand::new();
hand.add_card(card).unwrap();
// Information
let size = hand.size();
let is_valid = hand.size() >= 5;
// String representation
println!("{}", hand.to_string()); // "As Ks Qs Js Ts"
```
### `Card`
Individual playing card representation.
#### Construction
```rust
// From string notation
let card = Card::from_string("As").unwrap();
let card = Card::from_string("Kh").unwrap();
// String representation
assert_eq!(card.to_string(), "As");
```
#### Properties
```rust
let rank = card.rank(); // Card rank (0-12)
let suit = card.suit(); // Card suit (0-3)
let index = card.index(); // Unique card index (0-51)
```
## Hand Ranking Values
### Category Extraction
```rust
// Extract hand category (bits 24-27)
let category = (hand_value & HandEval::HAND_CATEGORY_MASK) >> HandEval::HAND_CATEGORY_SHIFT;
// Extract relative value (bits 0-23)
let value = hand_value & HandEval::VALUE_MASK;
```
### Hand Categories
| Category | Value | Description |
|----------|-------|-------------|
| Straight Flush | 9 | Five cards in sequence, same suit |
| Four of a Kind | 8 | Four cards of same rank |
| Full House | 7 | Three of a kind + pair |
| Flush | 6 | Five cards, same suit |
| Straight | 5 | Five cards in sequence |
| Three of a Kind | 4 | Three cards of same rank |
| Two Pair | 3 | Two different pairs |
| One Pair | 2 | Two cards of same rank |
| High Card | 1 | No matching cards |
### Rank Value Ranges
| Hand Type | Rank Range | Count |
|-----------|------------|-------|
| Straight Flush | 368,793,253 - 371,292,191 | 40 |
| Four of a Kind | 184,396,629 - 368,793,252 | 624 |
| Full House | 92,198,315 - 184,396,628 | 3,744 |
| Flush | 46,099,158 - 92,198,314 | 5,108 |
| Straight | 23,049,579 - 46,099,157 | 10,200 |
| Three of a Kind | 11,524,790 - 23,049,578 | 54,912 |
| Two Pair | 5,762,395 - 11,524,789 | 123,552 |
| One Pair | 2,881,198 - 5,762,394 | 1,098,240 |
| High Card | 1 - 2,881,197 | 1,302,540 |
## Performance Characteristics
### Time Complexity
| Operation | Time Complexity | Notes |
|-----------|----------------|-------|
| 5-Card evaluation | O(1) | Direct table lookup |
| 6-Card evaluation | O(1) | 6 table lookups |
| 7-Card evaluation | O(1) | 21 table lookups |
| Table generation | O(N) | N = 32M combinations |
### Memory Usage
| Component | Size | Description |
|-----------|------|-------------|
| Hand ranks table | ~128 MB | Complete evaluation table |
| Working tables | ~2.4 MB | Generation workspace |
| Code size | ~50 KB | Compiled binary |
### Cache Performance
The lookup table design provides excellent cache performance:
- **Sequential Access**: Table generation processes data sequentially
- **Compact Encoding**: Cards encoded in 8 bits each
- **Prefetch Friendly**: Linear table layout enables hardware prefetching
- **Low Branch Misprediction**: Perfect hash eliminates conditional logic
## Error Handling
### Common Error Cases
```rust
// Invalid hand size
let rank = evaluator.rank_hand(&hand); // Returns 0 for < 5 cards
// Card parsing errors
let card = Card::from_string("XX"); // Returns Err
// Table loading errors
let evaluator = LookupHandEvaluator::new(); // May fail if disk full
```
### Error Types
- `io::Error` - File system errors during table loading/generation
- `CardParseError` - Invalid card string format
- `HandFullError` - Attempting to add cards to full hand
## Thread Safety
The `LookupHandEvaluator` is designed for read-only usage after construction:
```rust
// Safe: Read-only evaluator
let evaluator = LookupHandEvaluator::new().unwrap();
// Multiple threads can use the same evaluator
let rank1 = evaluator.rank_hand(&hand1);
let rank2 = evaluator.rank_hand(&hand2);
// NOT safe: Modifying evaluator during use
// (evaluator is not Sync + Send for mutation)
```
## Integration Examples
### Texas Hold'em Engine
```rust
use poker_api::hand_evaluator::LookupHandEvaluator;
use poker_api::api::{hand::Hand, card::Card};
struct HoldemEngine {
evaluator: LookupHandEvaluator,
}
impl HoldemEngine {
fn evaluate_board(&self, hole_cards: &[Card; 2], board: &[Card; 5]) -> u32 {
let mut all_cards = Vec::new();
all_cards.extend_from_slice(hole_cards);
all_cards.extend_from_slice(board);
let mut hand = Hand::new();
for card in all_cards {
hand.add_card(card).unwrap();
}
self.evaluator.rank_hand(&hand)
}
}
```
### Hand Range Analysis
```rust
use poker_api::hand_evaluator::LookupHandEvaluator;
struct RangeAnalyzer {
evaluator: LookupHandEvaluator,
}
impl RangeAnalyzer {
fn compare_hands(&self, hand1: &Hand, hand2: &Hand) -> std::cmp::Ordering {
let rank1 = self.evaluator.rank_hand(hand1);
let rank2 = self.evaluator.rank_hand(hand2);
rank1.cmp(&rank2)
}
}
```
## Testing Integration
### Unit Tests
```rust
#[cfg(test)]
mod tests {
use super::*;
use poker_api::hand_evaluator::LookupHandEvaluator;
#[test]
fn test_royal_flush() {
let evaluator = LookupHandEvaluator::new().unwrap();
let mut hand = Hand::new();
// Add A,K,Q,J,10 of same suit
let rank = evaluator.rank_hand(&hand);
assert!(rank > 368_793_253); // Royal flush range
}
}
```
### Benchmark Tests
```rust
#[cfg(test)]
mod benchmarks {
use super::*;
use std::time::Instant;
#[test]
fn benchmark_evaluation() {
let evaluator = LookupHandEvaluator::new().unwrap();
let hand = create_test_hand();
let start = Instant::now();
for _ in 0..1_000_000 {
let _rank = evaluator.rank_hand(&hand);
}
let duration = start.elapsed();
println!("1M evaluations in {:?}", duration);
}
}
```
## Advanced Configuration
### Custom Table Paths
The evaluator uses default paths, but this can be customized by modifying the source:
```rust
// In hand_evaluator.rs
const FILE_NAME: &'static str = "custom/path/HandRanks.dat";
```
### Memory Management
For systems with limited memory, consider:
```rust
// Use Box<[u32]> for heap allocation control
let hand_ranks: Box<[u32]> = vec![0; SIZE].into_boxed_slice();
// Monitor memory usage
println!("Table memory usage: {} MB",
std::mem::size_of_val(&*hand_ranks) / 1_048_576);
```
### Performance Tuning
For maximum performance:
```rust
// Use release mode
cargo build --release
// Consider SIMD optimizations for batch evaluation
// (requires custom implementation)
```
This API documentation covers the complete public interface for poker hand evaluation. For implementation details, see the source code comments and the developer guide.

# Developer Guide
## Architecture Overview
The Poker Hand Evaluator implements the **Meerkat algorithm** for perfect hash-based poker hand evaluation. This section covers the internal architecture, algorithms, and design decisions.
## System Architecture
### Core Components
```

│ LookupHandEvaluator │
│ ┌─────────────────────────────────────────────────┐ │
│ │ Hand Ranking Table │ │
│ │ (32M+ entries) │ │
│ └─────────────────────────────────────────────────┘ │

│ │ Algorithm Modules │ │
│ │ • Flushes • Products • Unique • Values │ │
│ └─────────────────────────────────────────────────┘ │
└─────────────────────────────────────────────────────────┘
```
### Data Flow
1. **Table Generation** (one-time):
```
Card Combinations → Perfect Hash → Hand Evaluation → Rank Storage
```
2. **Hand Evaluation** (runtime):
```
Input Hand → Perfect Hash → Table Lookup → Rank Value
```
## Algorithm Details
### Perfect Hash Function
The core innovation is a perfect hash function that maps every possible card combination to a unique index:
```rust
fn perfect_hash(cards: &[u32]) -> usize {
let mut hash = 53u32; // Initial value
for &card in cards {
let index = card.index();
hash = TABLE[(hash + index + 1) as usize] as u8;
}
hash as usize
}
```
**Key Properties:**
- **Perfect**: No collisions for valid inputs
- **Minimal**: Uses minimal memory for given input size
- **Fast**: O(1) computation time
- **Deterministic**: Same input always produces same output
### Card Encoding
Each card is encoded using multiple techniques:
```rust
struct EncodedCard {
prime: u32, // Prime number for rank (2, 3, 5, 7, 11, ...)
rank_bits: u32, // Bit position for rank identification
suit_bits: u32, // Bit mask for suit detection
meta_bits: u32, // Additional metadata bits
}
```
**Prime Encoding:**
```rust
const PRIMES: [u32; 13] = [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41];
let prime = PRIMES[rank]; // Unique prime for each rank
```
### Hand Evaluation Strategy
#### 5-Card Hands
Direct evaluation using specialized lookup tables:
```rust
fn evaluate_5card(cards: [u32; 5]) -> u32 {
// 1. Check for flush
if is_flush(cards) {
return FLUSH_TABLE[flush_index(cards)];
}
// 2. Check for unique hands (straight flush, quads, etc.)
let unique_index = unique_hash(cards);
if let Some(rank) = UNIQUE_TABLE.get(unique_index) {
return rank;
}
// 3. Standard hand evaluation
let product_index = prime_product(cards);
VALUES_TABLE[product_index]
}
```
#### 6-7 Card Hands
Brute force evaluation of all 5-card combinations:
```rust
fn evaluate_7card(cards: [u32; 7]) -> u32 {
let mut best_rank = 0;
// Generate all C(7,5) = 21 combinations
for combination in combinations(cards, 5) {
let rank = evaluate_5card(combination);
best_rank = best_rank.max(rank);
}
best_rank
}
```
## Implementation Details
### Table Generation Process
#### Phase 1: Card Combination Enumeration
```rust
const TABLE_SIZE: usize = 612_978; // All possible combinations
for key in 0..TABLE_SIZE {
let cards = decode_key_to_cards(key);
// Validate card combination
if is_valid_combination(cards) {
let rank = evaluate_hand(cards);
table[key] = rank;
}
}
```
#### Phase 2: Perfect Hash Construction
The perfect hash is constructed by:
1. **Initial Mapping**: Map card combinations to initial hash values
2. **Conflict Resolution**: Resolve collisions using secondary tables
3. **Optimization**: Minimize table size while maintaining perfection
#### Phase 3: Table Serialization
```rust
fn save_tables(table: &[u32]) -> Result<(), io::Error> {
let file = File::create("math/HandRanks.dat")?;
let mut writer = BufWriter::new(file);
for &rank in table {
writer.write_all(&rank.to_ne_bytes())?;
}
Ok(())
}
```
### Memory Layout
#### Runtime Table Structure
```
┌─────────────────────────────────────────────────────────┐
│ HandRanks.dat │
├─────────────────────────────────────────────────────────┤
│ Entry 0: [u32] Rank for combination 0 │
│ Entry 1: [u32] Rank for combination 1 │
│ ... │
│ Entry N: [u32] Rank for combination N │
└─────────────────────────────────────────────────────────┘
↑
│
32,487,834 entries × 4 bytes = 129,951,336 bytes
```
#### Generation Working Tables
```rust
struct WorkingTables {
// Main ranking table during generation
hand_ranks: Box<[u32; 612_978]>,
// Specialized evaluation tables
flushes: FlushesTable,
products: ProductsTable,
unique: UniqueTable,
values: ValuesTable,
}
```
## Performance Optimizations
### SIMD Opportunities
Current implementation is scalar, but offers SIMD optimization potential:
```rust
// Potential SIMD optimization (future enhancement)
#[cfg(target_feature = "avx2")]
fn evaluate_hands_simd(hands: &[Hand]) -> Vec<u32> {
// Process multiple hands in parallel using AVX instructions
// Each hand evaluation becomes a vector operation
}
```
### Memory Access Patterns
The current design optimizes for:
- **Sequential Generation**: Tables generated in linear order
- **Random Access Evaluation**: O(1) lookup for any hand
- **Cache Efficiency**: Compact data structures for better cache utilization
### Algorithmic Optimizations
#### Hand-Specific Algorithms
Different hand types use specialized evaluation methods:
```rust
impl HandEvaluator {
fn evaluate_straight_flush(cards: [u32; 5]) -> u32 {
// Optimized straight flush detection
let ranks = extract_ranks(cards);
if is_consecutive(ranks) && is_same_suit(cards) {
calculate_straight_flush_rank(ranks[0])
} else {
0 // Not a straight flush
}
}
fn evaluate_four_of_a_kind(cards: [u32; 5]) -> u32 {
// Optimized quad detection using prime products
let product = calculate_prime_product(cards);
QUAD_TABLE[product]
}
}
```
## Testing Strategy
### Unit Tests
```rust
#[cfg(test)]
mod unit_tests {
use super::*;
#[test]
fn test_royal_flush() {
let hand = create_royal_flush();
let rank = evaluator.rank_hand(&hand);
assert!(is_royal_flush_rank(rank));
}
#[test]
fn test_perfect_hash() {
// Verify no hash collisions
let mut seen = HashSet::new();
for combination in all_possible_combinations() {
let hash = perfect_hash(combination);
assert!(!seen.contains(&hash));
seen.insert(hash);
}
}
}
```
### Integration Tests
```rust
#[cfg(test)]
mod integration_tests {
use super::*;
#[test]
fn test_vs_reference_implementation() {
let evaluator = LookupHandEvaluator::new().unwrap();
// Test against known reference implementation
for _ in 0..1_000_000 {
let hand = generate_random_hand();
let our_rank = evaluator.rank_hand(&hand);
let ref_rank = reference_evaluate(&hand);
assert_eq!(our_rank, ref_rank);
}
}
}
```
### Performance Benchmarks
```rust
#[cfg(test)]
mod benchmarks {
use super::*;
use std::time::Instant;
#[test]
fn benchmark_hand_evaluation() {
let evaluator = LookupHandEvaluator::new().unwrap();
let hands = generate_test_hands(1_000_000);
let start = Instant::now();
for hand in hands {
let _rank = evaluator.rank_hand(&hand);
}
let duration = start.elapsed();
println!("1M evaluations in {:?}", duration);
println!("Average: {:?} per hand", duration / 1_000_000);
}
}
```

```
## Mathematical Background
### Combinatorics
#### Card Combination Space
| Cards | Combinations | Calculation |
|-------|--------------|-------------|
| 5-Card | 2,598,960 | C(52,5) |
| 6-Card | 20,358,520 | C(52,6) |
| 7-Card | 133,784,560 | C(52,7) |
#### Table Size Calculation
```
Working Table: C(52,5) + C(52,6) + C(52,7) = 156,741,540 entries
Final Table: 32,487,834 unique combinations (after deduplication)
```
### Hash Function Design
The perfect hash function uses:
1. **Initial Value**: 53 (empirically chosen)
2. **Recursive Application**: Each card updates the hash
3. **Table Lookup**: Final mapping through ranking table
```rust
fn perfect_hash(cards: &[u32]) -> u32 {
let mut hash = 53;
for &card in cards {
let card_index = card.index();
hash = TABLE[(hash + card_index + 1) as usize] as u8;
}
hash as u32
}
```
## Future Enhancements
### Potential Improvements
1. **SIMD Optimization**: Vectorize hand evaluation for batch processing
2. **Memory Mapping**: Use memory-mapped files for table loading
3. **Compression**: Reduce table size using compression techniques
4. **Hardware Acceleration**: GPU-accelerated evaluation for massive scale
5. **Distributed Generation**: Parallel table generation across multiple machines
### Research Directions
1. **Alternative Hash Functions**: Explore more efficient perfect hash constructions
2. **Machine Learning**: Use ML to optimize evaluation algorithms
3. **Hardware Design**: Custom ASIC for poker hand evaluation
4. **Algorithmic Improvements**: Reduce computational complexity further

# User Guide
## Introduction
This guide explains how to use the Poker Hand Evaluator library for evaluating poker hands in your applications. Whether you're building a poker game, analysis tool, or AI bot, this library provides the fast and accurate hand evaluation you need.
## Quick Start
### Basic Setup
1. **Add dependency** to your `Cargo.toml`:
```toml
[dependencies]
poker-api = "0.1.0"
```
2. **Import and use** in your code:
```rust
use poker_api::hand_evaluator::LookupHandEvaluator;
use poker_api::api::hand::Hand;
fn main() -> Result<(), Box<dyn std::error::Error>> {
// Create the evaluator (generates tables on first run)
let evaluator = LookupHandEvaluator::new()?;
// Create a poker hand
let mut hand = Hand::new();
// ... add cards
// Evaluate the hand
let rank = evaluator.rank_hand(&hand);
println!("Hand strength: {}", rank);
Ok(())
}
```
### First Run Experience
On the first run, you'll see:
```
Evaluation tables do not exist, generating them...
Generating state table...
Hand evaluation tables saved to math/HandRanks.dat
Evaluation tables loaded.
```
This generates the lookup tables (~1-2 seconds) and saves them for future use.
## Working with Cards
### Card Creation
Cards can be created from string notation:
```rust
use poker_api::api::card::Card;
// Face cards
let ace_spades = Card::from_string("As")?;
let king_hearts = Card::from_string("Kh")?;
// Number cards
let five_clubs = Card::from_string("5c")?;
let ten_diamonds = Card::from_string("Td")?;
// All suits: s (spades), h (hearts), d (diamonds), c (clubs)
// All ranks: A, K, Q, J, T, 9, 8, 7, 6, 5, 4, 3, 2
```
### Card Properties
```rust
let card = Card::from_string("As")?;
println!("Rank: {}", card.rank()); // 12 (Ace)
println!("Suit: {}", card.suit()); // 0 (Spades)
println!("Index: {}", card.index()); // 51 (unique card ID)
println!("String: {}", card.to_string()); // "As"
```
## Working with Hands
### Creating Hands
```rust
use poker_api::api::hand::Hand;
use poker_api::api::card::Card;
// Create empty hand
let mut hand = Hand::new();
// Add cards one by one
hand.add_card(Card::from_string("As")?).unwrap();
hand.add_card(Card::from_string("Ks")?).unwrap();
hand.add_card(Card::from_string("Qs")?).unwrap();
hand.add_card(Card::from_string("Js")?).unwrap();
hand.add_card(Card::from_string("Ts")?).unwrap();
println!("Hand size: {}", hand.size()); // 5
println!("Hand: {}", hand.to_string()); // "As Ks Qs Js Ts"
```
### Hand Evaluation
```rust
// 5-card hand evaluation
let rank = evaluator.rank_hand(&hand);
println!("Royal flush rank: {}", rank);
// 6-card hand (finds best 5-card combination)
let mut six_card_hand = Hand::new();
six_card_hand.add_card(Card::from_string("As")?).unwrap();
six_card_hand.add_card(Card::from_string("Ks")?).unwrap();
// ... add 4 more cards
let rank = evaluator.rank_hand(&six_card_hand);
// 7-card hand (Texas Hold'em)
let mut seven_card_hand = Hand::new();
// ... add 7 cards
let rank = evaluator.rank_hand(&seven_card_hand);
```
## Understanding Hand Ranks
### Rank Values
Higher rank values indicate stronger hands:
```rust
// Compare hand strengths
let hand1_rank = evaluator.rank_hand(&hand1);
let hand2_rank = evaluator.rank_hand(&hand2);
if hand1_rank > hand2_rank {
println!("Hand 1 is stronger");
} else if hand1_rank < hand2_rank {
println!("Hand 2 is stronger");
} else {
println!("Hands are equal");
}
```
### Hand Categories
Extract hand category from rank:
```rust
use poker_api::api::hand_eval::HandEval;
fn get_hand_category(rank: u32) -> u32 {
(rank & HandEval::HAND_CATEGORY_MASK) >> HandEval::HAND_CATEGORY_SHIFT
}
let category = get_hand_category(rank);
match category {
9 => println!("Straight Flush"),
8 => println!("Four of a Kind"),
7 => println!("Full House"),
6 => println!("Flush"),
5 => println!("Straight"),
4 => println!("Three of a Kind"),
3 => println!("Two Pair"),
2 => println!("One Pair"),
1 => println!("High Card"),
_ => println!("Unknown"),
}
```
## Texas Hold'em Example
Here's a complete example of evaluating Texas Hold'em hands:
```rust
use poker_api::hand_evaluator::LookupHandEvaluator;
use poker_api::api::hand::Hand;
use poker_api::api::card::Card;
struct PokerGame {
evaluator: LookupHandEvaluator,
}
impl PokerGame {
fn new() -> Result<Self, Box<dyn std::error::Error>> {
Ok(Self {
evaluator: LookupHandEvaluator::new()?,
})
}
fn evaluate_texas_holdem(
&self,
hole_cards: &[Card; 2],
board: &[Card; 5]
) -> u32 {
let mut hand = Hand::new();
// Add hole cards
hand.add_card(hole_cards[0]).unwrap();
hand.add_card(hole_cards[1]).unwrap();
// Add community cards
for &card in board {
hand.add_card(card).unwrap();
}
self.evaluator.rank_hand(&hand)
}
}
fn main() -> Result<(), Box<dyn std::error::Error>> {
let game = PokerGame::new()?;
// Example: Royal Flush
let hole_cards = [
Card::from_string("As").unwrap(),
Card::from_string("Ks").unwrap(),
];
let board = [
Card::from_string("Qs").unwrap(),
Card::from_string("Js").unwrap(),
Card::from_string("Ts").unwrap(),
Card::from_string("2d").unwrap(),
Card::from_string("3c").unwrap(),
];
let rank = game.evaluate_texas_holdem(&hole_cards, &board);
println!("Royal flush rank: {}", rank);
Ok(())
}
```
## Performance Optimization
### Table Preloading
For applications that need immediate response:
```rust
// Warm up the evaluator before use
fn preload_evaluator() -> LookupHandEvaluator {
println!("Loading poker evaluator...");
let start = std::time::Instant::now();
let evaluator = LookupHandEvaluator::new().unwrap();
let duration = start.elapsed();
println!("Evaluator ready in {:?}", duration);
evaluator
}
```
### Batch Evaluation
For evaluating many hands:
```rust
fn evaluate_multiple_hands(evaluator: &LookupHandEvaluator, hands: &[Hand]) -> Vec<u32> {
hands.iter()
.map(|hand| evaluator.rank_hand(hand))
.collect()
}
```
## Error Handling
### Common Errors
```rust
use poker_api::api::card::Card;
// Invalid card strings
let invalid = Card::from_string("XX"); // Err
let invalid = Card::from_string("53"); // Err
// Hand capacity exceeded
let mut hand = Hand::new();
// Adding more than 7 cards will fail
// Table loading failures
let evaluator = LookupHandEvaluator::new();
// May fail if disk is full or permissions are insufficient
```
### Proper Error Handling
```rust
use std::io;
fn create_evaluator() -> Result<LookupHandEvaluator, io::Error> {
match LookupHandEvaluator::new() {
Ok(evaluator) => {
println!("Evaluator created successfully");
Ok(evaluator)
}
Err(e) => {
eprintln!("Failed to create evaluator: {}", e);
Err(e)
}
}
}
```
## Best Practices
### 1. Reuse Evaluators
```rust
// Good: Reuse the same evaluator
struct GameEngine {
evaluator: LookupHandEvaluator,
}
impl GameEngine {
fn new() -> Result<Self, io::Error> {
Ok(Self {
evaluator: LookupHandEvaluator::new()?,
})
}
fn evaluate_hand(&self, hand: &Hand) -> u32 {
self.evaluator.rank_hand(hand)
}
}
```
### 2. Validate Input Data
```rust
fn safe_evaluate_hand(evaluator: &LookupHandEvaluator, hand: &Hand) -> Option<u32> {
if hand.size() >= 5 && hand.size() <= 7 {
Some(evaluator.rank_hand(hand))
} else {
None
}
}
```
### 3. Handle Edge Cases
```rust
// Check for invalid hands
let rank = evaluator.rank_hand(&hand);
if rank == 0 {
println!("Invalid hand: must have 5-7 cards");
}
```
## Integration Examples
### Poker Bot
```rust
use poker_api::hand_evaluator::LookupHandEvaluator;
struct PokerBot {
evaluator: LookupHandEvaluator,
}
impl PokerBot {
fn should_raise(&self, my_hand: &Hand, pot_odds: f32) -> bool {
let hand_strength = self.evaluator.rank_hand(my_hand);
// Simple strategy: raise with strong hands
match hand_strength {
rank if rank > 300_000_000 => true, // Very strong
rank if rank > 100_000_000 => pot_odds > 0.1, // Medium strength
_ => false, // Weak hands
}
}
}
```
### Hand Range Analysis
```rust
use poker_api::hand_evaluator::LookupHandEvaluator;
use poker_api::api::hand::Hand;
struct RangeAnalyzer {
evaluator: LookupHandEvaluator,
}
impl RangeAnalyzer {
fn analyze_range(&self, hands: &[Hand]) -> HandStrengthStats {
let ranks: Vec<u32> = hands.iter()
.map(|hand| self.evaluator.rank_hand(hand))
.collect();
HandStrengthStats {
average_rank: ranks.iter().sum::<u32>() / ranks.len() as u32,
median_rank: self.calculate_median(&ranks),
strongest_hand: ranks.iter().max().copied().unwrap_or(0),
weakest_hand: ranks.iter().min().copied().unwrap_or(0),
}
}
}
```
## Troubleshooting
### Common Issues
**Problem**: "Evaluation tables do not exist, generating them..." every time
**Solution**: Ensure write permissions in the current directory, or specify a custom path
**Problem**: Slow first startup
**Solution**: Expected behavior - table generation takes 1-2 seconds
**Problem**: High memory usage
**Solution**: The 128MB lookup table is required for performance. Consider if this fits your deployment constraints
**Problem**: Card parsing fails
**Solution**: Verify card strings use correct format: rank + suit (e.g., "As", "Kh", "Td")
### Performance Issues
If evaluation seems slow:
1. **Check build mode**: Use `cargo build --release`
2. **Verify table loading**: Ensure tables are generated and cached
3. **Monitor memory**: Ensure sufficient RAM for table storage
4. **Consider batching**: Evaluate multiple hands together when possible
