Struct pest::prelude::Token [−] [src]

pub struct Token<Rule> {
    pub rule: Rule,
    pub start: usize,
    pub end: usize,
}

A struct representing tokens generated by a parser.

Fields

rule: Rule

matched Rule

start: usize

starting position in Input

end: usize

ending position in Input

Methods

impl<Rule> Token<Rule>
[src]

fn new(rule: Rule, start: usize, end: usize) -> Token<Rule>

Creates a new Token.

Examples

impl_rdp! {
    grammar! {
        expression = _{ paren ~ expression? }
        paren      =  { ["("] ~ expression? ~ [")"] }
    }
}

let token = Token::new(Rule::paren, 0, 1);

assert_eq!(token.rule, Rule::paren);
assert_eq!(token.start, 0);
assert_eq!(token.end, 1);
