Struct rusty_lr::Parser

pub struct Parser<Term, NonTerm> {
    pub rules: Vec<ProductionRule<Term, NonTerm>>,
    pub states: Vec<State<Term, NonTerm>>,
}

struct for Deterministic Finite Automaton (DFA).

It contains Vec of production rules and states.

Fields

rules: Vec<ProductionRule<Term, NonTerm>>

states: Vec<State<Term, NonTerm>>

Implementations

impl<Term, NonTerm> Parser<Term, NonTerm>

pub fn feed<'a>( &'a self, context: &mut Context, term: Term, ) -> Result<(), ParseError<'a, Term, NonTerm, u8, u8>>

where Term: Hash + Eq, NonTerm: Hash + Eq,

feed one terminal to parser, and update state stack

pub fn feed_callback<'a, C>( &'a self, context: &mut Context, callback: &mut C, term: Term, ) -> Result<(), ParseError<'a, Term, NonTerm, <C as Callback<Term, NonTerm>>::Error, u8>>

where C: Callback<Term, NonTerm>, Term: Hash + Eq, NonTerm: Hash + Eq,

feed one terminal to parser, and update state stack

pub fn begin(&self) -> Context
