There was a problem hiding this comment.
As mentioned in the tracking issue, since MaybeUninit only supports Sized types, we need a separate block because <T: PointeeSized> is still too lax for MaybeUninit.

Looks good, thanks! @bors r+ rollup |

Rollup merge of #145325 - clarfonthey:cast-init, r=scottmcm Add `cast_init` and `cast_uninit` methods for pointers ACP: rust-lang/libs-team#627 Tracking issue: #145036 This includes an incredibly low-effort search to find uses that could be switched to using these methods. I only searched for `cast::<\w>` and `cast::<MaybeUninit` because there would otherwise be way too much to look through, and I also didn't modify anything inside submodules/subtrees.
