Module ast 

AST representation and pattern extraction data structures.

This module provides language-agnostic AST representations and specialized structures for pattern detection in different programming languages.

Design Pattern Extraction

The module supports extracting design patterns from source code:

• Class hierarchies with inheritance and decorators
• Method definitions with abstract/override tracking
• Module-level singleton instances
• Assignment and expression analysis

Example

use debtmap::core::ast::{ClassDef, ModuleScopeAnalysis};

// Extract classes from Python AST
let classes: Vec<ClassDef> = extractor.extract_classes(&module);

// Analyze module scope for singletons
let scope: ModuleScopeAnalysis = extractor.extract_module_scope(&module);

Performance Considerations

Pattern extraction is designed to add minimal overhead (< 5%) to existing parsing operations by extracting data during the single-pass AST traversal.
