Struct TreeSitterParser 

pub struct TreeSitterParser { /* private fields */ }

A reusable Tree-sitter parser and direct typed-CST lowerer.

Implementations

impl TreeSitterParser

pub fn new() -> Result<Self, ParseError>

Creates a parser loaded with the bundled Macaulay2 grammar.

Errors

Returns ParseError::Language if Tree-sitter rejects the bundled language definition.

pub fn parse_recovering( &mut self, source: &str, ) -> Result<Recovered<SourceFile, LexError>, ParseError>

Parses incomplete source while retaining syntax inside unclosed groups.

The parsing view is completed only for Tree-sitter; reconstructed nodes retain the original source spans and zero-width missing closers.

Errors

Returns ParseError when source has a non-recoverable lexical or grammatical failure, parsing is cancelled, or lowering fails.

Trait Implementations

impl Parser for TreeSitterParser

type Error = ParseError

The backend-specific parse failure.

fn parse_stream( &mut self, tokens: TokenStream, ) -> Result<SourceFile, Self::Error>

Parses tokens into one typed syntax target.
