Function nom::number::streaming::recognize_float

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

Recognizes a floating point number in text format and returns the corresponding part of the input

streaming version: will return Err(nom::Err::Incomplete(_)) if it reaches the end of input
