Function winnow::number::streaming::f32

pub fn f32<I, E: ParseError<I>>(
    endian: Endianness
) -> fn(_: I) -> IResult<I, f32, E>where
    I: Stream<Token = u8>,
    <I as Stream>::Slice: AsBytes,

👎Deprecated since 0.1.0: Replaced with <code>winnow::number::f32</code> with input wrapped in <code>winnow::Partial</code>

Recognizes a 4 byte floating point number

If the parameter is winnow::number::Endianness::Big, parse a big endian f32 float, otherwise if winnow::number::Endianness::Little parse a little endian f32 float. Partial version: Will return Err(winnow::error::ErrMode::Incomplete(_)) if there is not enough data.
