pub fn new() -> Self

pub fn get_tree(&mut self, path: &Path) -> Option<(Tree, Lang)>

Parse a file and return its AST tree + detected language. Uses cache if the file hasn’t been modified since last parse. Parse a file and return its AST tree + detected language. Uses cache if the file hasn’t been modified since last parse.

pub fn parse_source(&mut self, source: &str, lang: Lang) -> Option<Tree>

Parse source code directly (not from file). No caching.

pub fn invalidate(&mut self, path: &Path)

Invalidate cache for a specific file (e.g. after edit_file).

pub fn clear(&mut self)

Clear entire cache.
