Function nom::number::complete::be_i24

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

Recognizes a big endian signed 3 bytes integer.

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