Function mshio::parsers::recognize_integer

pub fn recognize_integer<I, E: ParseError<I>>(i: I) -> IResult<I, I, E> where
    I: Clone + Offset + Slice<RangeTo<usize>> + Slice<RangeFrom<usize>> + InputIter + InputTakeAtPosition,
    <I as InputIter>::Item: AsChar,
    <I as InputTakeAtPosition>::Item: AsChar, 

Consumes an integer
