[−][src]Trait logos::source::WithSource
Marker trait for any Logos, which will constrain it to a specific subset of
Sources.
In particular, if your token definitions would allow reading invalid UTF-8,
the Logos derive macro will restrict you to lexing on Sources that also
implement the BinarySource marker (&[u8] is provided).
Note: You shouldn't implement this trait yourself, #[derive(Logos)] will
do it for you.
