Function nom::number::streaming::be_f32

pub fn be_f32<I, E: ParseError<I>>(input: I) -> IResult<I, f32, E> where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength, 

Recognizes a big endian 4 bytes floating point number.

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