Trait LanguageParser 

pub trait LanguageParser: Send + Sync {
    // Required methods
    fn language(&self) -> Language;
    fn extensions(&self) -> &[&str];
    fn extract_nodes(
        &self,
        tree: &Tree,
        source: &str,
        file_path: &str,
    ) -> Vec<CodeNode>;
}

Trait for language-specific parsing logic.

Each language needs to implement this to handle its unique AST structure and idioms. The trait provides the Tree-sitter language and the extraction logic.

Required Methods

fn language(&self) -> Language

Returns the Tree-sitter language for this parser.

fn extensions(&self) -> &[&str]

File extensions this parser handles.

fn extract_nodes( &self, tree: &Tree, source: &str, file_path: &str, ) -> Vec<CodeNode>

Extracts CodeNodes from a parsed Tree-sitter tree.

This is where the magic happens. Each language traverses its AST differently to find functions, classes, etc.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
