Function nom::number::complete::i16

pub fn i16<'a, E: ParseError<&'a [u8]>>(
    endian: Endianness
) -> fn(_: &'a [u8]) -> IResult<&'a [u8], i16, E>

Recognizes a signed 2 byte integer

If the parameter is nom::Endianness::Big, parse a big endian i16 integer, otherwise if nom::Endianness::Little parse a little endian i16 integer. complete version: returns an error if there is not enough input data
