Expand description

Parses the bytes s using cmp to compare each token.

If you have a stream implementing RangeStream such as &[u8] you can also use the range parser which may be more efficient.

let result = bytes_cmp(&b"abc"[..], |l, r| l.eq_ignore_ascii_case(&r))
    .parse(&b"AbC"[..]);
assert_eq!(result, Ok((&b"abc"[..], &b""[..])));
