Specifically, change `Region` from this: ``` pub type Region<'tcx> = &'tcx RegionKind; ``` to this: ``` pub struct Region<'tcx>(&'tcx Interned<RegionKind>); ``` This now matches `Ty` and `Predicate` more closely. Things to note - Regions have always been interned, but we haven't been using pointer-based `Eq` and `Hash`. This is now happening. - I chose to impl `Deref` for `Region` because it makes pattern matching a lot nicer, and `Region` can be viewed as just a smart wrapper for `RegionKind`. - Various methods are moved from `RegionKind` to `Region`. - There is a lot of tedious sigil changes. - A couple of types like `HighlightBuilder`, `RegionHighlightMode` now have a `'tcx` lifetime because they hold a `Ty<'tcx>`, so they can call `mk_region`. - A couple of test outputs change slightly, I'm not sure why, but the new outputs are a little better. |
