Struct LR0StateMachine

Source
pub struct LR0StateMachine<'a, T: 'a, N: 'a, A: 'a> {
    pub states: Vec<(ItemSet<'a, T, N, A>, BTreeMap<&'a Symbol<T, N>, usize>)>,
    pub start: &'a N,
}
Expand description

An LR(0) state machine.

Fields§

§states: Vec<(ItemSet<'a, T, N, A>, BTreeMap<&'a Symbol<T, N>, usize>)>

A vector of states, each of which consists of an item set and a set of transitions.

State 0 is the starting state.

§start: &'a N

The starting state of the associated context-free grammar.
