Implementations§

source§

impl<'a, StorageT: 'static + Debug + Hash + PrimInt + Unsigned, LexerTypesT: LexerTypes<StorageT = StorageT>> RTParserBuilder<'a, StorageT, LexerTypesT>
where usize: AsPrimitive<StorageT>,

source

pub fn new( grm: &'a YaccGrammar<StorageT>, stable: &'a StateTable<StorageT> ) -> Self

Create a new run-time parser from a YaccGrammar, and a StateTable.

source

pub fn recoverer(self, rk: RecoveryKind) -> Self

Set the recoverer for this parser to rk.

source

pub fn term_costs(self, f: &'a dyn Fn(TIdx<StorageT>) -> u8) -> Self

source

pub fn parse_generictree( &self, lexer: &dyn NonStreamingLexer<'_, LexerTypesT> ) -> (Option<Node<LexerTypesT::LexemeT, StorageT>>, Vec<LexParseError<StorageT, LexerTypesT>>)

Parse input, and (if possible) return a generic parse tree. See the arguments for parse_actions for more details about the return value.

source

pub fn parse_noaction( &self, lexer: &dyn NonStreamingLexer<'_, LexerTypesT> ) -> Vec<LexParseError<StorageT, LexerTypesT>>

Parse input, returning any errors found. See the arguments for parse_actions for more details about the return value.

source

pub fn parse_actions<'b: 'a, 'input: 'b, ActionT: 'a, ParamT: Copy>( &self, lexer: &'b dyn NonStreamingLexer<'input, LexerTypesT>, actions: &'a [&'a dyn Fn(RIdx<StorageT>, &'b dyn NonStreamingLexer<'input, LexerTypesT>, Span, Drain<'_, AStackType<<LexerTypesT as LexerTypes>::LexemeT, ActionT>>, ParamT) -> ActionT], param: ParamT ) -> (Option<ActionT>, Vec<LexParseError<StorageT, LexerTypesT>>)

Parse input, execute actions, and return the associated value (if possible) and/or any lexing/parsing errors encountered. Note that the two parts of the (value, errors) return pair are entirely independent: one can encounter errors without a value being produced (None, [...]), errors and a value (Some(...), [...]), as well as a value and no errors (Some(...), []). Errors are sorted by the position they were found in the input and can be a mix of lexing and parsing errors.
