Function nom::number::streaming::be_i8

pub fn be_i8<I, E: ParseError<I>>(input: I) -> IResult<I, i8, E> where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength, 

Recognizes a signed 1 byte integer.

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

use nom::number::streaming::be_i8;

let parser = be_i8::<_, (_, ErrorKind)>;

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