- `rq`: RQ level limit
|
||||
|
||||
**Example**:
|
||||
```rust

print_best_car(&"laguna".to_string(), &"Dry".to_string(), &"85".to_string());
|
||||
```
|
||||
|
||||
##### `print_trash()`

**Purpose**: Collection optimization recommendations
|
||||
|
||||
**Safety Criteria**:
|
||||
- Car not among best performers on any track
|
||||
- RQ level below 80 (preserves high-end cars)
|
||||
- Not a prize car (may have collection value)
|
||||
|
||||
**Output Format**:

||||
```
|
||||
|
||||
**Purpose**: Core parsing logic for individual car performance data
|
||||
|
||||
**Process Flow**:
|
||||
1. Load car's JSON timing file
|
||||
2. Parse each configuration (111, 233, 323, etc.)
|
||||
3. Extract timing data for each track/condition
|
||||
4. Apply quality filters (downvotes, time validation)
|
||||
5. Update global best cars cache
|
||||
|
||||
**Quality Filters**:
|
||||

|
||||
- Updates records for improved performance
|
||||
|
||||
**Logic**:
|
||||
1. For each RQ level from car_rq to 115:
|
||||
2. If new time is better → replace record
|
||||
3. If new time ties → add to list (if not duplicate)
|

## Usage Examples
|
||||
|
||||
### Basic Analysis Workflow
|
||||
|
||||
```rust
|
||||
// 1. Load user's car collection
|
||||
let my_cars = get_my_car_list();
|
||||
|
||||
// 2. Process all car timing data
|
||||
parse_all_times().await;
|
||||
|
||||
// 3. Generate best cars report
|
||||
print_best_cars(false);
|
||||
|
||||
// 4. Find collection optimization opportunities
|
||||
print_trash();
|
||||
```
|
||||
|
||||
### Track-Specific Analysis
|
||||
|
||||
```rust
|
||||
// Analyze specific track conditions
|
||||
let track = "laguna".to_string();
|
||||
let condition = "Dry".to_string();
|
||||
let rq = "85".to_string();
|
||||
|
||||
print_best_car(&track, &condition, &rq);
|
||||
```
|
||||
|
||||
### Data Fetching
|
||||
|
||||
```rust
|
||||
// Download fresh data
|
||||
get_cars_file().await;
|
||||
get_tracks_file().await;
|
||||
fetch_times().await;
|
||||
```
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### Time Complexity
|
||||
- **Parsing**: O(n) where n = number of cars × tracks
|
||||
- **Best Car Selection**: O(1) HashMap operations
|
||||
- **Sorting**: O(n log n) for output ordering
|
||||
|
||||
### Memory Usage
|
||||
- **Peak**: ~200-300MB during full analysis
|
||||
- **Baseline**: ~50MB application overhead
|
||||
- **Per Car**: ~1-2KB metadata + timing data
|
||||
|
||||
### Concurrency
|
||||
- **Downloads**: 20 concurrent connections max
|
||||
- **Processing**: One task per car file
|
||||
- **Thread Safety**: Mutex-protected shared state
|
||||
|
||||

**"Function not found"**
|
||||
- Check module imports
|
||||
- Verify function signatures
|
||||
- Ensure proper visibility
|
||||
|
||||
**"Type mismatch"**
|
||||
- Review struct field types
|
||||
- Check function signatures
|
||||
- Verify generic parameters
|
||||
|
||||
**"Deadlock"**
|
||||
- Avoid nested Mutex locks
|
||||
- Check lock ordering
|
||||
- Use timeout where possible
|
||||
|
||||
### Debug Strategies
|
||||
|
||||
**Logging**:
|
||||
```rust
|
||||
println!("Processing car: {}", car.rid);
|
||||
eprintln!("Error: {}", error);
|
||||
```
|
||||
|
||||
**Tracing**:
|
||||
```rust
|
||||
// Add at function entry
|
||||
let _span = tracing::span!(Level::INFO, "function_name");
|
||||
let _enter = _span.enter();
|
||||
```
|
||||
|
||||
**Profiling**:
|
||||
```bash
|
||||
cargo flamegraph --bin records -- best
|
||||
```
|

# Architecture Documentation
|
||||
|
||||
## System Overview
|
||||
|
||||
The Top Drives Records Analyzer consists of two main components working together to provide comprehensive car performance analysis for the Top Drives racing game.
|
||||
|
||||
## Component Architecture
|
||||
|
||||
### 1. Records Module (`src/records.rs`)
|
||||
|
||||
**Primary analysis engine** that processes pre-downloaded JSON timing data.
|
||||
|
||||
#### Key Responsibilities
|
||||
- **Data Fetching**: Downloads car and track databases from GitHub repository
|
||||
- **File Processing**: Parses JSON timing files for each car configuration
|
||||
- **Performance Analysis**: Compares timing data across RQ ranges and track conditions
|
||||
- **Collection Management**: Identifies owned cars and optimization opportunities
|
||||
|
||||
#### Data Flow
|
||||
|
||||
```
|
||||
GitHub Repository
|
||||
↓
|
||||
cars_repo.json + tracks_repo.json
|
||||
↓
|
||||
times/*.json (1000+ car files)
|
||||
↓
|
||||
JSON Parsing → BestCarRecord Analysis
|
||||
↓
|
||||
User Collection (my_cars.json)
|
||||
↓
|
||||
Output: CSV/Terminal Results
|
||||
```
|
||||
|
||||
### 2. Club Module (`src/club.rs`)
|
||||
|
||||
**Alternative data source** that scrapes live data from topdrives.club website.
|
||||
|
||||
#### Key Responsibilities
|
||||
- **Web Scraping**: Fetches HTML content from topdrives.club
|
||||
- **HTML Parsing**: Extracts car performance data using CSS selectors
|
||||
- **Real-time Data**: Provides fresh data without pre-downloaded files
|
||||
|
||||
#### Data Flow
|
||||
|
||||
```
|
||||
topdrives.club Website
|
||||
↓
|
||||
HTML Content
|
||||
↓
|
||||
CSS Selector Parsing
|
||||
↓
|
||||
Car Data Extraction
|
||||
↓
|
||||
Output: Terminal Results
|
||||
```
|
||||
|
||||
## Data Structures
|
||||
|
||||
### Core Types
|
||||
|
||||
#### TripletKey
|
||||
```rust
|
||||
type TripletKey = (String, u8, String);
|
||||
// ↓ ↓ ↓
|
||||
// Track ID RQ Level Surface Condition
|
||||
```
|
||||
|
||||
**Purpose**: Composite key for uniquely identifying track conditions
|
||||
**Usage**: HashMap key for storing best car records
|
||||
|
||||
#### Car (Records Module)
|
||||
```rust
|
||||
struct Car {
|
||||
rid: String, // Repository ID
|
||||
brand: String, // Manufacturer
|
||||
only_name: String, // Model name
|
||||
year: u16, // Model year
|
||||
rq: u8, // Rarity level
|
||||
prize: bool, // Prize car status
|
||||
guid: String, // Game GUID
|
||||
}
|
||||
```
|
||||
|
||||
#### BestCarRecord
|
||||
```rust
|
||||
struct BestCarRecord {
|
||||
car_rid: String, // Car identifier
|
||||
brand: String, // Manufacturer
|
||||
only_name: String, // Model name
|
||||
year: u16, // Year
|
||||
rq: u8, // RQ level
|
||||
config: String, // Tune config (111, 233, etc.)
|
||||
time: f64, // Track time (seconds)
|
||||
owned: bool, // User ownership status
|
||||
guid: String, // Game identifier
|
||||
}
|
||||
```
|
||||
|
||||
#### Car (Club Module)
|
||||
```rust
|
||||
struct Car {
|
||||
class: String, // Class letter (S, A, B, etc.)
|
||||
rq: u8, // Rarity level
|
||||
manufacturer: String, // Brand
|
||||
model: String, // Model
|
||||
year: u16, // Year
|
||||
upgrade: String, // Upgrade config
|
||||
}
|
||||
```
|
||||
|
||||
## Global State Management
|
||||
|
||||
### BEST_CARS Cache
|
||||
```rust
|
||||
static BEST_CARS: Lazy<Mutex<HashMap<TripletKey, Vec<BestCarRecord>>>>
|
||||
```
|
||||
|
||||
**Thread Safety**: Protected by `Mutex` for concurrent access during parsing
|
||||
**Initialization**: Uses `once_cell::Lazy` for one-time setup
|
||||
**Structure**: HashMap with composite keys for efficient lookups
|
||||
|
||||
## Algorithm Details
|
||||
|
||||
### RQ Range Analysis
|
||||
|
||||
The system analyzes car performance across multiple RQ brackets:
|
||||
|
||||
1. **Base RQ**: Car's natural rarity level
|
||||
2. **RQ Range**: Tests from car's RQ up to maximum (115)
|
||||
3. **Cross-RQ Competition**: Allows cars to compete above their base level
|
||||
|
||||
**Example**: A RQ 85 car might perform well at RQ 90-95 levels against higher-rated cars
|
||||
|
||||
### Time Validation
|
||||
|
||||
Multiple validation layers ensure data quality:
|
||||
|
||||
1. **Minimum Time**: Times below 1.2 seconds are discarded
|
||||
2. **Downvote Filter**: Community-downvoted times are excluded
|
||||
3. **Special Cases**: Test Bowl track uses inverted time calculation (2000.0 / time)
|
||||
|
||||
### Concurrent Processing
|
||||
|
||||
#### Records Module
|
||||
- **Task Spawning**: One async task per car file
|
||||
- **Rate Limiting**: Semaphore limits concurrent downloads (20 max)
|
||||
- **Error Isolation**: Individual car failures don't stop batch processing
|
||||
|
||||
#### Synchronization
|
||||
- **Join Handles**: Waits for all parsing tasks to complete
|
||||
- **Mutex Protection**: Safe concurrent access to shared BEST_CARS cache
|
||||
|
||||
## File Organization
|
||||
|
||||
### Input Files
|
||||
```
|
||||
├── cars_repo.json # Car database from repository
|
||||
├── tracks_repo.json # Track definitions
|
||||
├── my_cars.json # User's car collection (game export)
|
||||
└── times/ # Individual car timing files
|
||||
├── Ferrari_F40_1987.json
|
||||
├── McLaren_F1_1993.json
|
||||
└── ...
|
||||
```
|
||||
|
||||
### Output Files
|
||||
```
|
||||
├── best.csv # Best cars analysis results
|
||||
├── missing.csv # Missing recommended cars
|
||||
└── details.csv # Detailed timing data
|
||||
```
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### Records Module
|
||||
- **Startup Time**: Fast (uses cached JSON files)
|
||||
- **Memory Usage**: Moderate (loads all timing data into memory)
|
||||
- **Accuracy**: High (comprehensive dataset)
|
||||
- **Update Frequency**: Manual refresh required
|
||||
|
||||
### Club Module
|
||||
- **Startup Time**: Slow (web scraping required)
|
||||
- **Memory Usage**: Low (processes one track at a time)
|
||||
- **Accuracy**: Variable (depends on website structure)
|
||||
- **Update Frequency**: Real-time on each run
|
||||
|
||||
## Error Handling Strategy
|
||||
|
||||
### Graceful Degradation
|
||||
- **Missing Files**: Continue with available data
|
||||
- **Network Errors**: Log errors but don't crash
|
||||
- **Parse Failures**: Use default values or skip invalid entries
|
||||
|
||||
### User Feedback
|
||||
- **Progress Indication**: Shows fetching/download progress
|
||||
- **Error Messages**: Clear descriptions of what went wrong
|
||||
- **Fallback Options**: Multiple data sources available
|
||||
|
||||
## Extension Points
|
||||
|
||||
### Adding New Tracks
|
||||
1. Update `tracks_repo.json` with new track definitions
|
||||
2. Add track name mappings in `translate_track_name()`
|
||||
3. Add condition mappings in `translate_track_type()`
|
||||
|
||||
### Adding New Analysis Types
|
||||
1. Create new output functions (similar to `print_best_cars()`)
|
||||
2. Add command parsing in main function
|
||||
3. Update help text and documentation
|
||||
|
||||
### Custom Data Sources
|
||||
1. Implement new scraping module (similar to club.rs)
|
||||
2. Add data source selection logic
|
||||
3. Update configuration system
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Network Access
|
||||
- **HTTPS Only**: All external requests use HTTPS
|
||||
- **Certificate Validation**: Accepts invalid certificates for compatibility
|
||||
- **Rate Limiting**: Respects server limits with controlled concurrency
|
||||
|
||||
### Local File Access
|
||||
- **Read Only**: No modification of game files
|
||||
- **User Data**: Only reads exported collection data
|
||||
- **No Persistence**: Analysis results are output-only
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Potential Improvements
|
||||
1. **Caching Layer**: Cache web scraping results
|
||||
2. **Database Backend**: Replace in-memory HashMap with persistent storage
|
||||
3. **Configuration Files**: External configuration for analysis parameters
|
||||
4. **GUI Interface**: Web-based interface for non-technical users
|
||||
5. **Export Formats**: Multiple output formats (JSON, XML, etc.)
|
||||
|
||||
### Scalability Considerations
|
||||
1. **Pagination**: Handle large datasets with pagination
|
||||
2. **Incremental Updates**: Only fetch changed data
|
||||
3. **Compression**: Compress large timing files
|
||||
4. **Streaming**: Process data without loading everything into memory

||||
|
||||
**Purpose**: Master database of all cars in Top Drives with their metadata.
|
||||
|
||||
**Source**: Downloaded from `https://github.com/TiagoXavi/topdrives-records/raw/refs/heads/main/src/database/cars_final.json`
|
||||
|
||||
**Structure**:
|
||||
```json
|
||||
[
|
||||
{
|
||||
"rid": "Ferrari_F40_1987",
|
||||
"brand": "Ferrari",
|
||||
"onlyName": "F40",
|
||||
"year": 1987,
|
||||
"rq": 95,
|
||||
"prize": false,
|
||||
"guid": "card_ferrari_f40_1987"
|

|
||||
- Used to identify cars for timing file processing
|
||||
- Provides metadata for analysis output
|
||||
|
||||
### 2. User's Car Collection (`my_cars.json`)
|
||||
|
||||
**Purpose**: Contains the user's owned cars exported from the Top Drives game.
|
||||
|
||||
**Source**: Exported from Top Drives game (Settings → Account → Export Data)
|
||||
|
||||
**Structure**:
|
||||
```json
|
||||
{
|
||||
"playerDeck": [
|
||||
{
|
||||
"cardId": "card_ferrari_f40_1987",
|
||||
"locked": true
|
||||
},
|
||||
{
|
||||
"cardId": "card_mclaren_f1_1993",
|
||||
"locked": false
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|

|
||||
| `cardId` | String | Unique card identifier |
|
||||
| `locked` | Boolean | Whether card is owned (true = owned) |
|
||||
|
||||
**Processing Logic**:
|
||||
- Only `locked: true` cards are considered owned
|
||||
- `cardId` values are matched against car database GUIDs
|
||||
- Used to mark cars as "owned" in analysis results
|
||||
|
||||
### 3. Individual Car Timing Files (`times/{rid}.json`)
|
||||
|
||||
**Purpose**: Contains detailed timing data for a specific car across all tracks and conditions.
|
||||

||||
| `d` | String | Date/time of submission (optional) |
|
||||
|
||||
**Usage in Application**:
|
||||
- Processed by `parse_car_times()` function
|
||||
- Each track entry becomes a `BestCarRecord`
|
||||
- Downvoted times are filtered out for quality
|
||||
- Times below 1.2 seconds are considered invalid
|
||||
|
||||
### 4. Tracks Database (`tracks_repo.json`)

||||
**Usage in Application**:
|
||||
- Provides track name mappings for output
|
||||
- Used for track-specific analysis queries
|
||||
- Supports condition filtering
|
||||
|
||||
## Data Processing Pipeline
|
||||
|
||||
### 1. Data Acquisition Phase
|
||||
|
||||
**Files Downloaded:**
|
||||
1. `cars_repo.json` - Complete car database
|
||||
2. `tracks_repo.json` - Track definitions
|
||||
3. `times/{rid}.json` - Individual car timing data (1000+ files)
|
||||
|
||||
**Validation:**
|
||||
- HTTP response codes checked
|
||||
- JSON parsing errors handled gracefully
|
||||
- File corruption detection
|
||||
|
||||
### 2. Data Parsing Phase
|
||||
|
||||
**Car Database Processing:**
|
||||
```rust
|
||||
// Parse cars_repo.json
|
||||
let cars_data: Vec<Value> = serde_json::from_str(&file_content)?;
|
||||
for car in cars_data {
|
||||
let car = Car {
|
||||
rid: car["rid"].as_str().unwrap_or(""),
|
||||
brand: car["brand"].as_str().unwrap_or(""),
|
||||
// ... other fields
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
**Timing Data Processing:**
|
||||
```rust
|
||||
// Parse individual car timing file
|
||||
let json_data: Value = serde_json::from_str(&file_content)?;
|
||||
if let Some(configurations) = json_data["data"].as_object() {
|
||||
for (config, entry) in configurations {
|
||||
if let Some(times) = entry["times"].as_object() {
|
||||
for (track_id, details) in times {
|
||||
// Process each track time
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Data Transformation Phase
|
||||
|
||||
**Track ID Parsing:**
|
||||
- Input: `"laguna_a00"` (track + condition)
|
||||
- Process: Split on `"_a"` delimiter
|
||||
- Output: `("laguna", "00")` (track name, condition code)
|
||||
|
||||
**Condition Code Translation:**
|
||||
- `"00"` → `"Dry"`
|
||||
- `"01"` → `"Wet"`
|
||||
- `"10"` → `"Dirt"`
|
||||
- `"11"` → `"Dirt Wet"`
|
||||
|
||||
**Time Validation:**
|
||||
1. Check for downvotes: `details["down"].as_array()`
|
||||
2. Validate time range: `time > 1.2`
|
||||
3. Special handling: Test Bowl inversion `2000.0 / time`
|
||||
|
||||
### 4. Data Aggregation Phase
|
||||
|
||||
**Best Car Records Creation:**
|
||||
```rust
|
||||
BestCarRecord {
|
||||
car_rid: car.rid.clone(),
|
||||
brand: car.brand.clone(),
|
||||
only_name: car.only_name.clone(),
|
||||
year: car.year,
|
||||
rq: car.rq,
|
||||
config: config.clone(),
|
||||
time,
|
||||
owned: my_cars.contains(&car.guid),
|
||||
guid: car.guid.clone(),
|
||||
}
|
||||
```
|
||||
|
||||
**RQ Range Analysis:**
|
||||
- Test each car from its base RQ up to 115
|
||||
- Compare against existing best times
|
||||
- Update records if better performance found
|
||||
|
||||
## Data Quality Measures
|
||||
|
||||
### Validation Rules
|
||||
|
||||
1. **Time Thresholds**:
|
||||
- Minimum time: 1.2 seconds
|
||||
- Test Bowl: Inverted calculation (2000.0 / time)
|
||||
|
||||
2. **Community Validation**:
|
||||
- Downvoted times excluded
|
||||
- Multiple submissions required for reliability
|
||||
|
||||
3. **Data Consistency**:
|
||||
- Track name normalization
|
||||
- Condition code standardization
|
||||
- Car identifier validation
|
||||
|
||||
### Error Handling
|
||||
|
||||
**Network Errors**:
|
||||
- Failed downloads logged but don't stop processing
|
||||
- Existing cached data used as fallback
|
||||
- Clear error messages for user
|
||||
|
||||
**Parse Errors**:
|
||||
- Malformed JSON handled gracefully
|
||||
- Missing fields use default values
|
||||
- Invalid times filtered out
|
||||
|
||||
**File System Errors**:
|
||||
- Missing files reported clearly
|
||||
- Permission issues identified
|
||||
- Corrupt files detected and skipped
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Memory Usage
|
||||
|
||||
**Large Data Structures**:
|
||||
- `BEST_CARS` HashMap: Contains all best records across RQ ranges
|
||||
- Individual timing files: Loaded and parsed sequentially
|
||||
- User collection: Small, loaded once
|
||||
|
||||
**Optimization Strategies**:
|
||||
- Concurrent processing of car files
|
||||
- Rate-limited downloads (20 concurrent max)
|
||||
- Streaming JSON parsing where possible
|
||||
|
||||
### Processing Speed
|
||||
|
||||
**Bottlenecks**:
|
||||
1. **Network I/O**: 1000+ small files downloaded
|
||||
2. **JSON Parsing**: Each timing file parsed individually
|
||||
3. **HashMap Operations**: Frequent insertions with RQ range checking
|
||||
|
||||
**Optimizations Applied**:
|
||||
1. **Concurrency**: One task per car file
|
||||
2. **Connection Pooling**: Reuse HTTP connections
|
||||
3. **Early Filtering**: Invalid times rejected quickly
|
||||
|
||||
## Data Evolution
|
||||
|
||||
### Version Compatibility
|
||||
|
||||
**Backwards Compatibility**:
|
||||
- Old timing files still parseable
|
||||
- New fields added gracefully
|
||||
- Deprecated fields handled
|
||||
|
||||
**Schema Evolution**:
|
||||
- New track additions supported
|
||||
- Condition code extensions possible
|
||||
- Car metadata fields expandable
|
||||
|
||||
### Update Strategy
|
||||
|
||||
**Incremental Updates**:
|
||||
- Only changed cars need re-downloading
|
||||
- Track database updated periodically
|
||||
- User collection refreshed as needed
|
||||
|
||||
**Data Freshness**:
|
||||
- Community timing data updates frequently
|
||||
- Car database relatively stable
|
||||
- Track definitions rarely change
|
||||
|
||||
## Troubleshooting Data Issues
|
||||
|
||||
### Common Problems
|
||||
|
||||
**Missing Timing Data**:
|
||||
- **Symptom**: Cars show no performance data
|
||||
- **Cause**: Timing file not downloaded or corrupted
|
||||
- **Solution**: Re-run `fetch` command
|
||||
|
||||
**Incorrect Ownership**:
|
||||
- **Symptom**: Wrong cars marked as owned/missing
|
||||
- **Cause**: Outdated `my_cars.json` export
|
||||
- **Solution**: Re-export from Top Drives game
|
||||
|
||||
**Track Name Issues**:
|
||||
- **Symptom**: Unknown track codes in output
|
||||
- **Cause**: Outdated track definitions
|
||||
- **Solution**: Update `tracks_repo.json`
|
||||
|
||||
### Data Validation Tools
|
||||
|
||||
**Integrity Checks**:
|
||||
1. **File Count**: Verify expected number of timing files
|
||||
2. **JSON Validity**: Parse all files for syntax errors
|
||||
3. **Reference Integrity**: Cross-check car and track references
|
||||
|
||||
**Diagnostic Commands**:
|
||||
```bash
|
||||
# Check for missing timing files
|
||||
ls times/ | wc -l # Should be 1000+
|
||||
|
||||
# Validate JSON syntax
|
||||
find times/ -name "*.json" -exec jq empty {} \;
|
||||
|
||||
# Check for common issues
|
||||
grep -r "No RID" times/
|
||||
```
|
||||
|
||||
## Future Data Structure Enhancements
|
||||
|
||||
### Potential Improvements
|
||||
|
||||
1. **Compression**: Gzip timing files to reduce storage
|
||||
2. **Indexing**: Add database indexes for faster queries
|
||||
3. **Caching**: Cache parsed data to avoid re-processing
|
||||
4. **Incremental Updates**: Only download changed files
|
||||
|
||||
### Schema Extensions
|
||||
|
||||
**Additional Fields**:
|
||||
- Car weight and dimensions
|
||||
- Performance curves
|
||||
- Weather condition effects
|
||||
- Driver skill impact
|
||||
|
||||
**New Analysis Types**:
|
||||
- Historical performance trends
|
||||
- Meta change impact analysis
|
||||
- Community submission quality metrics
|
||||
- Regional performance differences

||||
### Cargo.toml Analysis
|
||||
|
||||
**Project Structure:**
|
||||
```toml
|
||||
[package]
|
||||
name = "top_drives"
|
||||
version = "0.2.0"
|
||||
edition = "2021"
|
||||
|
||||
[[bin]]
|
||||
name = "club"
|
||||
path = "src/club.rs"
|
||||
|
||||
[[bin]]
|
||||
name = "records"
|
||||
path = "src/records.rs"
|
||||
```
|
||||
|
||||
**Binary Configuration:**
|
||||
- **records**: Main analysis tool (JSON-based)
|
||||
- **club**: Alternative scraper (web-based)
|
||||
|
||||
**Dependency Versions:**
|
||||
- All dependencies pinned to specific versions for reproducibility
|
||||
- Compatible versions tested together
|
||||
- Security updates monitored
|
||||
|
||||
## Performance Optimization
|
||||
|
||||
### Compilation Settings
|
||||
|
||||
**Debug Build:**
|
||||
```bash
|
||||
cargo build # Fast compilation, slow execution
|
||||
```
|
||||
|
||||
**Release Build:**
|
||||
```bash
|
||||
cargo build --release # Slow compilation, fast execution
|
||||
```
|
||||
|
||||
**Profile Configuration** (Optional `Cargo.toml`):
|
||||
```toml
|
||||
[profile.release]
|
||||
opt-level = 3
|
||||
lto = true
|
||||
codegen-units = 1
|
||||
panic = "abort"
|
||||
```
|
||||
|
||||
### Runtime Performance
|
||||
|
||||
**Memory Settings:**
|
||||
```bash
|
||||
# Increase stack size for deep recursion (if needed)
|
||||
RUST_MIN_STACK=8388608 cargo run
|
||||
|
||||
# Enable backtraces for debugging
|
||||
RUST_BACKTRACE=1 cargo run
|
||||
```
|
||||
|
||||
**Concurrency Tuning:**
|
||||
- Default: 20 concurrent downloads (configurable via Semaphore)
|
||||
- Thread count: Automatic based on CPU cores
|
||||
- Memory usage: ~100-200MB for full dataset
|
||||
|
||||
## Testing Setup
|
||||
|
||||
### Running Tests
|
||||
```bash
|
||||
cargo test # Run all tests
|
||||
cargo test --release # Run tests on release build
|
||||
cargo test -- --nocapture # Show test output
|
||||
```
|
||||
|
||||
### Writing Tests
|
||||
|
||||
**Example Test Structure:**
|
||||
```rust
|
||||
#[cfg(test)]
|
||||
mod tests {
|
||||
use super::*;
|
||||
|
||||
#[tokio::test]
|
||||
async fn test_parse_car_times() {
|
||||
// Test implementation
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Test Data:**
|
||||
- Create sample JSON files in `tests/fixtures/`
|
||||
- Mock HTTP responses for network tests
|
||||
- Use `tempfile` crate for temporary files
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Installation Issues
|
||||
|
||||
**"rustc not found"**
|
||||
- **Cause**: Rust not in PATH
|
||||
- **Solution**: Add `$HOME/.cargo/bin` to PATH
|
||||
|
||||
**"Permission denied" (Unix)**
|
||||
- **Cause**: Insufficient permissions
|
||||
- **Solution**: Check file permissions or use `sudo` for system-wide install
|
||||
|
||||
**"Linker not found" (Linux)**
|
||||
- **Cause**: Missing build tools
|
||||
- **Solution**: Install `build-essential` (Ubuntu) or `gcc` (CentOS)
|
||||
|
||||
### Build Issues
|
||||
|
||||
**"Package not found"**
|
||||
- **Cause**: Missing dependencies
|
||||
- **Solution**: Run `cargo fetch` or `cargo build` with internet
|
||||
|
||||
**"Conflicting versions"**
|
||||
- **Cause**: Dependency version conflicts
|
||||
- **Solution**: Update Cargo.lock with `cargo update`
|
||||
|
||||
**"Compilation failed"**
|
||||
- **Cause**: Syntax or type errors
|
||||
- **Solution**: Check error messages, fix code issues
|
||||
|
||||
### Runtime Issues
|
||||
|
||||
**"Thread panicked"**
|
||||
- **Cause**: Unhandled error conditions
|
||||
- **Solution**: Add proper error handling, check unwrap() calls
|
||||
|
||||
**"Out of memory"**
|
||||
- **Cause**: Large dataset processing
|
||||
- **Solution**: Process data in batches, increase system memory
|
||||
|
||||

|
||||
|
||||
## Advanced Usage
|
||||
|
||||
### RQ Range Analysis
|
||||
|
||||
The tool analyzes performance across RQ brackets. Understanding RQ ranges:
|
||||
|
||||
- **RQ 10-50**: Entry level cars
|
||||
- **RQ 51-80**: Mid-tier performance
|
||||
- **RQ 81-100**: High performance
|
||||
- **RQ 101-113**: Elite/supercars
|
||||
|
||||
**Strategy:**
|
||||
- Focus on 2-3 RQ brackets where you race most
|
||||
- Identify cars that perform well across multiple brackets
|
||||
- Consider upgrade paths for favorite cars
|
||||
|
||||
### Collection Planning
|
||||
|
||||
#### Step 1: Assess Current Collection
|
||||
```bash
|
||||
cargo run --bin records -- best
|
||||
```
|
||||
- Identify your strongest cars
|
||||
- Note RQ distribution
|
||||
- Find gaps in coverage
|
||||
|
||||
#### Step 2: Identify Priorities
|
||||
```bash
|
||||
cargo run --bin records -- missing
|
||||
```
|
||||
- Focus on high-count cars in your RQ range
|
||||
- Consider track variety needs
|
||||
- Factor in prize car availability
|
||||
|
||||
#### Step 3: Optimize Collection
|
||||
```bash
|
||||
cargo run --bin records -- trash
|
||||
```
|
||||
- Remove redundant low performers
|
||||
- Free up space for better cars
|
||||
- Maintain diversity for different track types
|
||||
|
||||
### Track Type Strategy
|
||||
|
||||
Different cars excel on different track types:
|
||||
|
||||
#### Speed Tracks
|
||||
- **Characteristics**: Long straights, high speeds
|
||||
- **Best cars**: High top speed, good acceleration
|
||||
- **Examples**: Laguna Seca, Monaco Streets
|
||||
|
||||
#### Technical Tracks
|
||||
- **Characteristics**: Tight corners, elevation changes
|
||||
- **Best cars**: Good handling, braking
|
||||
- **Examples**: Deals Gap, Mountain Hairpin
|
||||
|
||||
#### Off-Road Tracks
|
||||
- **Characteristics**: Dirt, gravel, snow surfaces
|
||||
- **Best cars**: Good grip, durability
|
||||
- **Examples**: Desert Rally, Forest Road
|
||||
|
||||
## Output File Analysis
|
||||
|
||||
### CSV File Usage
|
||||
|
||||
The tool generates CSV files for external analysis:
|
||||
|
||||
#### best.csv
|
||||
- Your best performing cars
|
||||
- Import into spreadsheet for sorting/filtering
|
||||
- Track performance across time
|
||||
|
||||
#### missing.csv
|
||||
- Cars to acquire
|
||||
- Prioritize by count and RQ relevance
|
||||
- Plan acquisition strategy
|
||||
|
||||
#### details.csv
|
||||
- Comprehensive timing database
|
||||
- Advanced analysis and research
|
||||
- Historical performance tracking
|
||||
|
||||
### Spreadsheet Analysis Tips
|
||||
|
||||
**Excel/Google Sheets setup:**
|
||||
1. Import CSV files
|
||||
2. Create pivot tables by RQ, Brand, Track
|
||||
3. Add conditional formatting for high performers
|
||||
4. Create dashboards for collection overview
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### "Please provide a command"
|
||||
**Problem:** No arguments provided
|
||||
**Solution:** Use `best`, `missing`, `trash`, `details`, or `track`
|
||||
|
||||
#### "Could not read my cars file"
|
||||
**Problem:** `my_cars.json` not found or not readable
|
||||
**Solution:**
|
||||
1. Export fresh data from Top Drives game
|
||||
2. Ensure file is named exactly `my_cars.json`
|
||||
3. Check file permissions
|
||||
|
||||
#### "Failed to fetch the file"
|
||||
**Problem:** Network issues or API unavailable
|
||||
**Solution:**
|
||||
1. Check internet connection
|
||||
2. Try again later (may be temporary)
|
||||
3. Use existing cached data if available
|
||||
|
||||
#### No output or empty results
|
||||
**Problem:** Missing timing data or configuration issues
|
||||
**Solution:**
|
||||
1. Re-run `fetch` command to get fresh data
|
||||
2. Check that `times/` directory has files
|
||||
3. Verify `cars_repo.json` exists
|
||||
|
||||
### Performance Issues
|
||||
|
||||
#### Slow analysis
|
||||
- **Expected**: First run takes 2-3 minutes (downloads data)
|
||||
- **Subsequent runs**: Should be fast (uses cached data)
|
||||
- **Large datasets**: Details command processes all timing data
|
||||
|
||||
#### Memory usage
|
||||
- **Normal**: 100-200MB for full analysis
|
||||
- **High**: Details command loads all timing data
|
||||
- **Solution**: Use specific commands instead of details for large datasets
|
||||
|
||||
## Tips and Best Practices
|
||||
|
||||
### Regular Maintenance
|
||||
1. **Weekly**: Run `fetch` to get latest data
|
||||
2. **Monthly**: Review `missing` cars for new acquisitions
|
||||
3. **Quarterly**: Use `trash` to optimize collection
|
||||
|
||||
### Data-Driven Decisions
|
||||
1. **Trust the numbers**: Count-based recommendations are data-driven
|
||||
2. **Consider context**: Some cars may have strategic value beyond performance
|
||||
3. **Track changes**: Keep performance history for trend analysis
|
||||
|
||||
### Collection Strategy
|
||||
1. **Diversify**: Don't focus only on one RQ bracket
|
||||
2. **Specialize**: Identify your preferred track types
|
||||
3. **Balance**: Mix proven performers with potential upgrades
|
||||
