Struct lrpar::RTParserBuilder

pub struct RTParserBuilder<'a, StorageT: Eq + Hash> { /* fields omitted */ }

A run-time parser builder.

Methods

impl<'a, StorageT: 'static + Debug + Hash + PrimInt + Unsigned> RTParserBuilder<'a, StorageT> where
    usize: AsPrimitive<StorageT>,
    u32: AsPrimitive<StorageT>, 

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

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

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

Set the recoverer for this parser to rk.

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

pub fn parse_generictree(
    &self,
    lexer: &dyn Lexer<StorageT>
) -> (Option<Node<StorageT>>, Vec<LexParseError<StorageT>>)

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

pub fn parse_noaction(
    &self,
    lexer: &dyn Lexer<StorageT>
) -> Vec<LexParseError<StorageT>>

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

pub fn parse_actions<'input, ActionT: 'a>(
    &self,
    lexer: &'input (dyn Lexer<StorageT> + 'input),
    actions: &[&dyn Fn(RIdx<StorageT>, &'input (dyn Lexer<StorageT> + 'input), (usize, usize), Drain<AStackType<ActionT, StorageT>>) -> ActionT]
) -> (Option<ActionT>, Vec<LexParseError<StorageT>>)

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.
