Struct Parser
pub struct Parser { /* private fields */ }Expand description
Chumsky-based parser that converts tokens into an AST.
Implementations§
§impl ChumskyParser
impl ChumskyParser
pub fn new(tokens: Vec<Token>, interner: ThreadedRodeo) -> ChumskyParser
pub fn new(tokens: Vec<Token>, interner: ThreadedRodeo) -> ChumskyParser
Create a new parser from tokens and an interner produced by the lexer.
pub fn with_preview_features(
self,
features: HashSet<PreviewFeature, FxBuildHasher>,
) -> ChumskyParser
pub fn with_preview_features( self, features: HashSet<PreviewFeature, FxBuildHasher>, ) -> ChumskyParser
Set the preview features enabled for this parse. Required to use any
syntax gated behind a --preview flag (ADR-0005).
pub fn with_source(self, source: impl Into<String>) -> ChumskyParser
pub fn with_source(self, source: impl Into<String>) -> ChumskyParser
ADR-0089: attach the source text. Required to derive doc blocks
when the docs preview feature is enabled. Without it, LineDoc
tokens are silently dropped (same as the Phase 1 behavior).
pub fn parse(self) -> Result<(Ast, ThreadedRodeo), CompileErrors>
pub fn parse(self) -> Result<(Ast, ThreadedRodeo), CompileErrors>
Parse the tokens into an AST, returning the AST and the interner.
Returns all parse errors if parsing fails, not just the first one.
