Struct ParserPool 

Source 
pub struct ParserPool<'r> { /* private fields */ }
Expand description

Lazily initialized parser and query cache for a language registry.

Implementations§

Source§

impl<'r> ParserPool<'r>

Source

pub fn new(registry: &'r LanguageRegistry) -> Self

Creates an empty cache backed by registry.

Source

pub fn parser(&mut self, id: LanguageId) -> Option<&mut Parser>

Returns a parser for id, creating and configuring it on first use.

A grammar rejected by tree-sitter is cached as a permanent miss.

Source

pub fn tags_query(&mut self, id: LanguageId) -> Option<&Query>

Returns the compiled tags query for id.

Missing query sources and compilation failures are cached permanently.

Source

pub fn imports_query(&mut self, id: LanguageId) -> Option<&Query>

Returns the compiled query-based import extractor for id.

Custom extractors, missing queries, and compilation failures are cached as permanent misses.

Source

pub fn injections_query(&mut self, id: LanguageId) -> Option<&Query>

Returns the compiled injection query for id.

Missing query sources and compilation failures are cached permanently.
