Function rocket::mtls::oid::asn1_rs::nom::number::streaming::float

pub fn float<T, E>(input: T) -> Result<(T, f32), Err<E>>
where
    E: ParseError<T>,
    T: Slice<RangeFrom<usize>> + Slice<RangeTo<usize>> + Clone + Offset + InputIter + InputLength + InputTake + ParseTo<f32> + Compare<&'static str> + InputTakeAtPosition + AsBytes + for<'a> Compare<&'a [u8]>,

Available on crate feature mtls only.

Recognizes floating point number in text format and returns a f32.

Streaming version: Will return Err(nom::Err::Incomplete(_)) if there is not enough data.
