Expand description

Recognizes a hex-encoded integer.

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

    use nom::number::streaming::hex_u32;

    let parser = |s| {
      hex_u32(s)
    };

    assert_eq!(parser(b"01AE;"), Ok((&b";"[..], 0x01AE)));
    assert_eq!(parser(b"abc"), Err(Err::Incomplete(Needed::new(1))));
    assert_eq!(parser(b"ggg"), Err(Err::Error((&b"ggg"[..], ErrorKind::IsA))));
