Struct PrattParser 

pub struct PrattParser<L: Language> { /* private fields */ }

Pratt parser: supports prefix/infix/postfix (postfix left for language layer special handling)

Implementations

impl<L: Language> PrattParser<L>

where L::SyntaxKind: Copy + PartialEq,

pub fn new() -> Self

Creates a new Pratt parser

pub fn prefix( &mut self, op: L::SyntaxKind, info: OperatorInfo, node_kind: L::SyntaxKind, ) -> &mut Self

Registers a prefix operator

pub fn infix( &mut self, op: L::SyntaxKind, info: OperatorInfo, node_kind: L::SyntaxKind, ) -> &mut Self

Registers an infix operator

pub fn parse<S, F>( &self, state: &mut ParserState<'_, S, L>, min_bp: Precedence, primary: &F, ) -> Arc<GreenNode<L::SyntaxKind>>

where S: Source, F: Fn(&mut ParserState<'_, S, L>) -> Arc<GreenNode<L::SyntaxKind>>,

Parses expressions using the Pratt algorithm

• min_bp: Minimum binding strength (precedence)
• primary: Primary expression parser provided by language layer (includes parentheses, literals, identifiers, and high-binding suffixes like calls/fields)
