impl<'s> Logos<'s> for Token

Source§

type Error = ()

Error type returned by the lexer. This can be set using #[logos(error = MyError)]. Defaults to () if not set.
Source§

type Extras = ()

Associated type Extras for the particular lexer. This can be set using #[logos(extras = MyExtras)] and accessed inside callbacks.
Source§

type Source = str

Source type this token can be lexed from. This will default to str, unless one of the defined patterns explicitly uses non-unicode byte values or byte slices, in which case that implementation will use [u8].
Source§

fn lex(lex: &mut Lexer<'s, Self>)

The heart of Logos. Called by the Lexer. The implementation for this function is generated by the logos-derive crate.
Source§

fn lexer(source: &'source Self::Source) -> Lexer<'source, Self>
