Expand description

Recognizes a signed 1 byte integer

Note that endianness does not apply to 1 byte numbers. complete version: returns an error if there is not enough input data

use nom::number::complete::i8;

let parser = |s| {
  i8(s)
};

assert_eq!(parser(&b"\x00\x03abcefg"[..]), Ok((&b"\x03abcefg"[..], 0x00)));
assert_eq!(parser(&b""[..]), Err(Err::Error((&[][..], ErrorKind::Eof))));
