Struct ParserPool 

pub struct ParserPool { /* private fields */ }

Pool of tree-sitter parsers and compiled queries, one per language.

Parsers and queries are lazily created on first use and reused for subsequent operations. This avoids the overhead of creating new parsers/compiling queries for each file.

Implementations

impl ParserPool

pub fn new() -> Self

Create a new empty parser pool.

pub fn get_or_create_query(&mut self, lang: SupportedLanguage) -> Option<&Query>

Get or create a compiled highlight query for the given language.

Queries are cached to avoid recompilation overhead on each use. This is particularly important for injection processing (e.g., Svelte) where multiple queries are needed per file.

pub fn get_or_create(&mut self, ext: &str) -> Option<&mut Parser>

Get or create a parser for the given file extension.

Returns None if the extension is not supported by tree-sitter.

pub fn supports_extension(ext: &str) -> bool

Check if tree-sitter supports the given file extension.

Trait Implementations

impl Default for ParserPool

fn default() -> Self

Returns the “default value” for a type.
