# Rust-Analyzer Semantic Analysis Dataset

This dataset contains comprehensive semantic analysis data extracted from the rust-analyzer codebase using our custom rust-analyzer integration. It captures the step-by-step processing phases that rust-analyzer performs when analyzing Rust code.

## Dataset Overview

This dataset provides unprecedented insight into how rust-analyzer (the most advanced Rust language server) processes its own codebase. It contains **500K+ records** across multiple semantic analysis phases.

### What's Included

- **Parsing Phase**: Syntax tree generation, tokenization, and parse error handling
- **Name Resolution Phase**: Symbol binding, scope analysis, and import resolution  
- **Type Inference Phase**: Type checking, inference decisions, and type error detection

### Dataset Statistics

- **Total Records**: ~533,000 semantic analysis events
- **Source Files**: 1,307 Rust files from rust-analyzer codebase
- **Data Size**: ~450MB in efficient Parquet format
- **Processing Phases**: 3 major compiler phases captured

## Dataset Structure

Each record contains:

- `id`: Unique identifier for the analysis event
- `file_path`: Source file being analyzed
- `line`, `column`: Location in source code
- `phase`: Processing phase (parsing, name_resolution, type_inference)
- `element_type`: Type of code element (function, struct, variable, etc.)
- `element_name`: Name of the element (if applicable)
- `syntax_data`: JSON-serialized syntax tree information
- `symbol_data`: JSON-serialized symbol resolution data
- `type_data`: JSON-serialized type inference information
- `source_snippet`: The actual source code being analyzed
- `context_before`/`context_after`: Surrounding code context
- `processing_time_ms`: Time taken for analysis
- `rust_version`, `analyzer_version`: Tool versions used

## Use Cases

### Machine Learning Applications
- **Code completion models**: Train on parsing and name resolution patterns
- **Type inference models**: Learn from rust-analyzer's type inference decisions
- **Bug detection models**: Identify patterns in diagnostic data
- **Code understanding models**: Learn semantic analysis patterns

### Research Applications  
- **Compiler optimization**: Analyze compilation patterns across large codebases
- **Language design**: Study how developers use Rust language features
- **IDE improvement**: Understand common semantic analysis patterns
- **Static analysis**: Develop better code analysis tools

### Educational Applications
- **Rust learning**: Understand how code is processed step-by-step
- **Compiler education**: Visualize semantic analysis phases
- **Code analysis tutorials**: Interactive examples of language server internals

## Data Quality

- ✅ **Schema validated**: All records follow consistent structure
- ✅ **Data integrity**: No corrupted or malformed records  
- ✅ **Completeness**: All processed files represented
- ✅ **Self-referential**: rust-analyzer analyzing its own codebase

## Technical Details

- **Format**: Parquet files for efficient storage and fast loading
- **Compression**: Snappy compression for optimal performance
- **Chunking**: Files split to stay under 10MB for Git LFS compatibility
- **Schema**: Strongly typed with proper null handling
