tree-sitter specific language trait

Required Methods

fn get_ts_language(&self) -> TSLanguage

tree sitter language to parse the source

Provided Methods

fn ast_grep<S: AsRef<str>>(&self, source: S) -> AstGrep<StrDoc<Self>>

Create an AstGrep instance for the language

fn injectable_languages(&self) -> Option<&'static [&'static str]>

fn extract_injections<L: LanguageExt>( &self, _root: Node<'_, StrDoc<L>>, ) -> HashMap<String, Vec<TSRange>>

get injected language regions in the root document. e.g. get JavaScripts in HTML it will return a list of tuples of (language, regions). The first item is the embedded region language, e.g. javascript The second item is a list of regions in tree_sitter. also see https://tree-sitter.github.io/tree-sitter/using-parsers#multi-language-documents

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
