Function nom8::number::be_i8

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

Recognizes a signed 1 byte integer.

Complete version: Returns an error if there is not enough input data.

Streaming version: Will return Err(nom8::Err::Incomplete(_)) if there is not enough data.

Example

use nom8::number::be_i8;

let parser = |s| {
  be_i8(s)
};

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

use nom8::number::be_i8;

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

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