Struct perplex::glr::RuleSlice

pub struct RuleSlice {
    pub rule: RuleId,
    pub from: usize,
    pub to: usize,
}

A resolution to a local ambiguity in a grammar.

Fields

rule: RuleId

The rule in the grammar this slice refers to.

from: usize

The first symbol of the slice, inclusive.

to: usize

The last symbol of the slice, exclusive.

Methods

impl RuleSlice
