Function nom::number::streaming::be_i16

pub fn be_i16<I, E: ParseError<I>>(input: I) -> IResult<I, i16, E> where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength, 

Recognizes a big endian signed 2 bytes integer.

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