a7a842027c even more unify Projection/Opaque in outlives code 2023-01-19 15:31:53 +03:00

68f12338af Rollup merge of #104505 - WaffleLapkin:no-double-spaces-in-comments, r=jackh726 
Remove double spaces after dots in comments

Most of the comments do not have double spaces, so I assume these are typos.

6b49435480 Rollup merge of #106829 - compiler-errors:more-alias-combine, r=spastorino 
Unify `Opaque`/`Projection` handling in region outlives code

They share basically identical paths in most places which are even easier to unify now that they're both `ty::Alias`

0f6e06b7c0 Lazily resolve type-alias-impl-trait defining uses 
by using an opaque type obligation to bubble up comparisons between opaque types and other types

Also uses proper obligation causes so that the body id works, because out of some reason nll uses body ids for logic instead of just diagnostics.

9835b90c91 Rollup merge of #92710 - jackh726:issue-92280, r=nikomatsakis 
Include Projections when elaborating TypeOutlives

Fixes #92280

In `Elaborator`, we elaborate that `Foo<<Bar as Baz>::Assoc>: 'a` -> `<Bar as Baz>::Assoc: 'a`. This is the same rule that would be applied to any other `Param`. If there are escaping vars, we continue to do nothing.

64716825b0 Rollup merge of #92191 - jackh726:issue-89352, r=nikomatsakis 
Prefer projection candidates instead of param_env candidates for Sized predicates

Fixes #89352

Also includes some drive by logging and verbose printing changes that I found useful when debugging this, but I can remove this if needed.

This is a little hacky - but imo no more than the rest of `candidate_should_be_dropped_in_favor_of`. Importantly, in a Chalk-like world, both candidates should be completely compatible.

r? ```@nikomatsakis```

375524014f Remove in_band_lifetimes from rustc_infer 
This crate actually had a typo `'ctx` in one of its functions:
```diff
-pub fn same_type_modulo_infer(a: Ty<'tcx>, b: Ty<'ctx>) -> bool {
+pub fn same_type_modulo_infer<'tcx>(a: Ty<'tcx>, b: Ty<'tcx>) -> bool {

24acf86029 Fix span for non-satisfied trivial trait bounds 
The spans for "trait bound not satisfied" errors in trivial trait bounds referenced the entire item (fn, impl, struct) before.
Now they only reference the obligation itself (`String: Copy`)
