Rollup merge of #53652 - oconnor663:copy_in_place, r=alexcrichton
define copy_within on slices This is a safe wrapper around `ptr::copy`, for regions within a single slice. Previously, safe in-place copying was only available as a side effect of `Vec::drain`. I've wanted this API a couple times in the past, and I figured I'd just whip up a PR to help discuss it. It's possible something like this exists elsewhere and I just missed it. It might also be a big enough addition to warrant an RFC, I'm not sure.
