Struct PrattParser 

pub struct PrattParser { /* private fields */ }

Precedence-climbing parser for the Algol surface: tokenizes infix source and parses it into LocatedExprTree forms using operator binding powers from its PrattTable.

Implementations

impl PrattParser

pub fn new(operators: PrattTable) -> Self

Creates a parser driven by the given operator table. Use crate::default_pratt_table for the standard arithmetic operators.

pub fn parse_text_tree( &self, codec: CodecId, source_id: impl Into<String>, source: &str, ) -> Result<LocatedExprTree>

Parses source into a located expression tree under a default decode budget. source_id names the input for origin tracking.

pub fn parse_text_tree_with_budget( &self, codec: CodecId, source_id: impl Into<String>, source: &str, budget: &mut DecodeBudget, ) -> Result<LocatedExprTree>

Parses source into a located expression tree under an explicit budget, erroring if any tokens remain after a complete expression.
