Struct slr_parser::Lexer[−][src]

pub struct Lexer<'l, 's> where
    's: 'l,  {
    pub cur_token: Option<Result<Token<'s>, Error>>,
    pub next_token: Option<Result<Token<'s>, Error>>,
    // some fields omitted
}

A type handling the lexing.

Fields

cur_token: Option<Result<Token<'s>, Error>>next_token: Option<Result<Token<'s>, Error>>

Implementations

impl<'l, 's> Lexer<'l, 's>[src]

pub fn new(source: &'l mut Source<'s>) -> Lexer<'l, 's>[src]

Creates a new lexer from a source. The source will be reset by this operation, and must not be used with any spans created from a previous lexing done with that source.

pub fn get_source(&self) -> &Source<'s>ⓘ
