Function nom::number::streaming::i128

pub fn i128<I, E: ParseError<I>>(
    endian: Endianness
) -> fn(_: I) -> IResult<I, i128, E> where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength, 

Recognizes a signed 16 byte integer

If the parameter is nom::number::Endianness::Big, parse a big endian i128 integer, otherwise if nom::number::Endianness::Little parse a little endian i128 integer. Streaming version: Will return Err(nom::Err::Incomplete(_)) if there is not enough data.
