Function `le_u8`

fn le_u8<I, E: ParseError<I>>(input: I) -> IResult<I, u8, E>
where
    I: Input<Item = u8>

Recognizes an unsigned 1 byte integer.

Streaming version: Will return Err(nom::Err::Incomplete(_)) if there is not enough data.

# use nom::{Err, error::ErrorKind, Needed};

assert_eq!(parser(&b"\x00\x01abcd"[..]), Ok((&b"\x01abcd"[..], 0x00)));
assert_eq!(parser(&b""[..]), Err(Err::Incomplete(Needed::new(1))));
