Function rocket::mtls::oid::asn1_rs::nom::number::complete::f32

pub fn f32<I, E>(endian: Endianness) -> fn(_: I) -> Result<(I, f32), Err<E>>
where
    E: ParseError<I>,
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength,

Available on crate feature mtls only.

Recognizes a 4 byte floating point number

If the parameter is nom::number::Endianness::Big, parse a big endian f32 float, otherwise if nom::number::Endianness::Little parse a little endian f32 float. complete version: returns an error if there is not enough input data
