Function recognize_float

Source 
pub fn recognize_float<T, E>(input: T) -> Result<(T, T), Err<E>>
where
    E: ParseError<T>,
    T: Slice<RangeFrom<usize>> + Slice<RangeTo<usize>> + Clone + Offset + InputIter + InputTakeAtPosition,
    <T as InputIter>::Item: AsChar,
    <T as InputTakeAtPosition>::Item: AsChar,
Available on crate feature mtls only.
Expand description

Recognizes floating point number in a byte string and returns the corresponding slice.

Complete version: Can parse until the end of input.

use nom::number::complete::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))));
