[−][src]Function nom::number::streaming::be_i32

pub fn be_i32<I, E: ParseError<I>>(input: I) -> IResult<I, i32, E> where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength,

Recognizes a big endian signed 4 bytes integer.

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

let parser = be_i32::<_, (_, ErrorKind)>;

assert_eq!(parser(&b"\x00\x01\x02\x03abcd"[..]), Ok((&b"abcd"[..], 0x00010203)));
assert_eq!(parser(&b""[..]), Err(Err::Incomplete(Needed::new(4))));
