Function recognize_float

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

    <T as InputTakeAtPosition>::Item: AsChar,
👎Deprecated since 8.0.0: Replaced with nom8::character::recognize_float with input wrapped in nom8::input::Streaming
Expand description

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

Streaming version: Will return Err(nom8::Err::Incomplete(_)) if it reaches the end of input.

use nom8::number::streaming::recognize_float;

let parser = |s| {
  recognize_float(s)
};

assert_eq!(parser("11e-1;"), Ok((";", "11e-1")));
assert_eq!(parser("123E-02;"), Ok((";", "123E-02")));
assert_eq!(parser("123K-01"), Ok(("K-01", "123")));
assert_eq!(parser("abc"), Err(Err::Error(("abc", ErrorKind::Char))));

WARNING: Deprecated, replaced with nom8::character::recognize_float with input wrapped in nom8::input::Streaming
