This crate provides input types for nom parser combinators using bitvec. With those, you can use common nom combinators directly on streams of bits.

Example

let data = [0xA5u8, 0x69, 0xF0, 0xC3];
let bits = data.view_bits::<Msb0>();

fn parser(bits: &BitSlice<Msb0, u8>) -> IResult<&BitSlice<Msb0, u8>, &BitSlice<Msb0, u8>> {
  tag(bits![1, 0, 1, 0])(bits)
}

assert_eq!(parser(bits), Ok((&bits[..4], &bits[4..])));
