Struct Lexer 

pub struct Lexer<'input, Iter: Iterator<Item = char> + Clone, Token, State, Error, Wrapper> {
    pub __state: usize,
    pub __done: bool,
    pub __initial_state: usize,
    pub __iter: Peekable<Iter>,
    /* private fields */
}

Common parts in lexers generated by lexgen.

Fields are used by lexgen-generated code and should not be used directly.

Fields

__state: usize

__done: bool

__initial_state: usize

__iter: Peekable<Iter>
