Function nom8::number::le_u24

pub fn le_u24<I, E: ParseError<I>, const STREAMING: bool>(
    input: I
) -> IResult<I, u32, E>where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength + InputIsStreaming<STREAMING>,

Recognizes a little endian unsigned 3 byte integer.

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::le_u24;

let parser = |s| {
  le_u24(s)
};

assert_eq!(parser(&b"\x00\x03\x05abcefg"[..]), Ok((&b"abcefg"[..], 0x050300)));
assert_eq!(parser(&b"\x01"[..]), Err(Err::Error((&[0x01][..], ErrorKind::Eof))));

use nom8::number::le_u24;

let parser = |s| {
  le_u24::<_, (_, ErrorKind), true>(s)
};

assert_eq!(parser(Streaming(&b"\x00\x01\x02abcd"[..])), Ok((Streaming(&b"abcd"[..]), 0x020100)));
assert_eq!(parser(Streaming(&b"\x01"[..])), Err(Err::Incomplete(Needed::new(2))));
