Expand description

Recognizes an unsigned 1 byte integer

Note that endianness does not apply to 1 byte numbers. Streaming version: Will return Err(nom::Err::Incomplete(_)) if there is not enough data.

use nom::number::streaming::u8;

let parser = |s| {
  u8::<_, (_, ErrorKind)>(s)

assert_eq!(parser(&b"\x00\x03abcefg"[..]), Ok((&b"\x03abcefg"[..], 0x00)));
assert_eq!(parser(&b""[..]), Err(Err::Incomplete(Needed::new(1))));
