Instead, how about adding a getraw() method?

e.g.

let g = Getch::new();
let byte: Result<u8> = g.getraw();

[kumavale]

If we implement the getraw() method for Getch, the input buffer will be half-finished.

e.g. input Up ("\x1b[A")

let g = Getch::new();
let byte: Result<u8> = g.getraw();
assert_eq!(byte, Ok(B'\x1b'));
let key: Reesult<Key> = g.getch();
assert_eq!(byte, Ok(Key::Char('[')));

Hmm...

I think it would be good to use as_bytes() to output something like the following.
