Function nom8::number::be_f64

pub fn be_f64<I, E: ParseError<I>, const STREAMING: bool>(
    input: I
) -> IResult<I, f64, E>where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength + InputIsStreaming<STREAMING>,

Recognizes a big endian 8 bytes floating point number.

Complete version: Returns an error if there is not enough input data.

Streaming version: Will return Err(nom8::Err::Incomplete(_)) if there is not enough data.

Example

use nom8::number::be_f64;

let parser = |s| {
  be_f64(s)
};

assert_eq!(parser(&[0x40, 0x29, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00][..]), Ok((&b""[..], 12.5)));
assert_eq!(parser(&b"abc"[..]), Err(Err::Error((&b"abc"[..], ErrorKind::Eof))));

use nom8::number::be_f64;

let parser = |s| {
  be_f64::<_, (_, ErrorKind), true>(s)
};

assert_eq!(parser(Streaming(&[0x40, 0x29, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00][..])), Ok((Streaming(&b""[..]), 12.5)));
assert_eq!(parser(Streaming(&[0x01][..])), Err(Err::Incomplete(Needed::new(7))));
