Function nom::character::streaming::i64

pub fn i64<T, E: ParseError<T>>(input: T) -> IResult<T, i64, E> where
    T: InputIter + Slice<RangeFrom<usize>> + InputLength + InputTake + Clone,
    <T as InputIter>::Item: AsChar,
    T: for<'a> Compare<&'a [u8]>, 

will parse a number in text form to a number
