How Parsing Works

Native Rust Parsing

Drift uses native Rust tree-sitter bindings for maximum performance:

1. Parse — Source code → Abstract Syntax Tree (native Rust)
2. Extract — Functions, classes, decorators, imports
3. Resolve — Call targets, data access points
4. Build — Call graph stored in SQLite

Performance: ~0.5ms per file (10x faster than WASM)

Hybrid Extraction

Drift combines AST parsing with regex fallback:

Source Code
    ↓
┌─────────────────┐
│  Tree-sitter    │ ← Primary (high confidence)
│  AST Parsing    │
└────────┬────────┘
         │
         ↓ (if fails)
┌─────────────────┐
│  Regex Fallback │ ← Secondary (lower confidence)
│  Extraction     │
└────────┬────────┘
         │
         ↓
   Call Graph + Patterns

Mixed-Language Projects

Drift handles polyglot codebases seamlessly:

# Scan everything
drift scan

# Scan specific language
drift scan --include "**/*.py"

# Scan multiple languages
drift scan --include "**/*.ts" --include "**/*.py"

Cross-Language Call Graph

The call graph connects across languages when possible:

• TypeScript frontend → Python API
• Go service → Rust library
• C# backend → C++ native module
