Implementations

impl<S> PrattCodecParser<S>

where S: PrattTokenSource,

pub fn new(operators: PrattTable, token_source: S) -> PrattCodecParser<S>

Creates a parser driven by operators and token_source.

pub fn with_surface_name( self, surface_name: &'static str, ) -> PrattCodecParser<S>

Sets the surface name used in parse error messages.

pub fn operators(&self) -> &PrattTable

Returns the parser’s operator table.

pub fn token_source(&self) -> &S

Returns the parser’s token source.

pub fn parse_tree( &self, codec: CodecId, source: &str, ) -> Result<LocatedExprTree, Error>

Parses source into a located expression tree under a default budget.

pub fn parse_tree_with_budget( &self, codec: CodecId, source: &str, budget: &mut DecodeBudget, ) -> Result<LocatedExprTree, Error>

Parses source into a located expression tree under an explicit budget.

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

Parses source into a located tree with the caller’s source id.

pub fn parse_tree_with_source_and_budget( &self, codec: CodecId, source_id: SourceId, source: &str, budget: &mut DecodeBudget, ) -> Result<LocatedExprTree, Error>

Parses source into a located tree with the caller’s source id and budget.
