Function nom8::number::be_i24

pub fn be_i24<I, E: ParseError<I>, const STREAMING: bool>(
    input: I
) -> IResult<I, i32, E>where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength + InputIsStreaming<STREAMING>,

Recognizes a big endian signed 3 bytes 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_i24;

let parser = |s| {
  be_i24(s)
};

assert_eq!(parser(&b"\x00\x03\x05abcefg"[..]), Ok((&b"abcefg"[..], 0x000305)));
assert_eq!(parser(&b"\x01"[..]), Err(Err::Error((&[0x01][..], ErrorKind::Eof))));

use nom8::number::be_i24;

let parser = be_i24::<_, (_, ErrorKind), true>;

assert_eq!(parser(Streaming(&b"\x00\x01\x02abcd"[..])), Ok((Streaming(&b"abcd"[..]), 0x000102)));
assert_eq!(parser(Streaming(&b""[..])), Err(Err::Incomplete(Needed::new(3))));
