Expand description

Counterpart to bits, bytes transforms its bit stream input into a byte slice for the underlying parser, allowing byte-slice parsers to work on bit streams.

A partial byte remaining in the input will be ignored and the given parser will start parsing at the next full byte.

fn parse(input: &[u8]) -> IResult<&[u8], (u8, u8, &[u8])> {
  bits::<_, _, Error<(&[u8], usize)>, _, _>(tuple((
    bytes::<_, _, Error<&[u8]>, _, _>(rest)

let input = &[0x12, 0x34, 0xff, 0xff];

assert_eq!(parse( input ), Ok(( &[][..], (0x01, 0x23, &[0xff, 0xff][..]) )));
