Dylan DPC d6f6084b24 Rollup merge of #95556 - declanvk:nonnull-provenance, r=dtolnay ... Implement provenance preserving methods on NonNull ### Description Add the `addr`, `with_addr`, `map_addr` methods to the `NonNull` type, and map the address type to `NonZeroUsize`. ### Motivation The `NonNull` type is useful for implementing pointer types which have the 0-niche. It is currently possible to implement these provenance preserving functions by calling `NonNull::as_ptr` and `new_unchecked`. The adding these methods makes it more ergonomic. ### Testing Added a unit test of a non-null tagged pointer type. This is based on some real code I have elsewhere, that currently routes the pointer through a `NonZeroUsize` and back out to produce a usable pointer. I wanted to produce an ideal version of the same tagged pointer struct that preserved pointer provenance. ### Related Extension of APIs proposed in #95228 . I can also split this out into a separate tracking issue if that is better (though I may need some pointers on how to do that).		2022-04-02 03:34:24 +02:00
