Struct CompiledExtraction 

pub struct CompiledExtraction { /* private fields */ }

A pre-compiled extraction that can be reused across multiple source inputs.

Stores compiled tree_sitter::Query objects and their capture names so they don’t need to be recompiled for every call. A QueryCursor is reused across patterns within a single extraction call, making this type Send + Sync.

Implementations

impl CompiledExtraction

pub fn compile(config: &ExtractionConfig) -> Result<Self, Error>

Compile an extraction config for repeated use.

Errors

Returns an error if the language is not found or any query pattern is invalid.

pub fn compile_with_language( language: Language, language_name: &str, extraction_patterns: &AHashMap<String, ExtractionPattern>, ) -> Result<Self, Error>

Compile extraction patterns using a pre-loaded tree_sitter::Language.

This avoids a redundant language registry lookup when the caller already has the language (e.g., from an earlier parse step).

Errors

Returns an error if any query pattern is invalid.

pub fn extract(&self, source: &str) -> Result<ExtractionResult, Error>

Extract from source code, parsing it first.

Uses the thread-local parser cache to avoid creating a new parser on every call.

Errors

Returns an error if parsing fails.

pub fn extract_from_tree( &self, tree: &Tree, source: &[u8], ) -> Result<ExtractionResult, Error>

Extract from an already-parsed tree.

Errors

Returns an error if query execution fails.
