Function nom::character::streaming::i128

pub fn i128<T, E: ParseError<T>>(input: T) -> IResult<T, i128, E>where
    T: InputIter + Slice<RangeFrom<usize>> + InputLength + InputTake + Clone + for<'a> Compare<&'a [u8]>,
    <T as InputIter>::Item: AsChar,

will parse a number in text form to a number

Complete version: can parse until the end of input.
