Expand description
§Bit Swap
This exchanges the bit-values in two locations. It is semantically and
behaviorally equivalent to BitRef::swap
, except that it works on
bit-pointer structures rather than proxy references. Prefer to use a proxy
reference or BitSlice::swap
instead.
§Original
§Safety
This has the same safety requirements as ptr::read
and ptr::write
,
as it is required to use them in its implementation.
§Examples
use bitvec::prelude::*;
use bitvec::ptr as bv_ptr;
let mut data = 2u8;
let x = BitPtr::<_, _, Lsb0>::from_mut(&mut data);
let y = unsafe { x.add(1) };
unsafe { bv_ptr::swap(x, y); }
assert_eq!(data, 1);
