2023-01-13Rollup merge of #106754 - compiler-errors:ty-infer-method-is-confusing, r=lcnrYuki Okushi-2/+5
Rename `Ty::is_ty_infer` -> `Ty::is_ty_or_numeric_infer` Makes sure people are aware that they may have a type variable *or* an int/float variable. r? `@oli-obk` https://github.com/rust-lang/rust/pull/106322#issuecomment-1376913539 but I could instead implement your solution, let me know. (This will conflict with #106322 for now, ignore that :smile:)

r=oli-obk Handle inference variables in `CollectAllMismatches` correctly 1. Fix #106240 2. Treat int/float type variables correctly (see `src/test/ui/iterators/invalid-iterator-chain-with-int-infer.rs`), so we can point out things like "`Iterator::Item` changed to `{integer}` here"

2023-01-11Rollup merge of #106170 - compiler-errors:autoderef-to-analysis, r=lcnrMichael Goulet-255/+24
Move autoderef to `rustc_hir_analysis` Not sure if this is a change we actually want, but autoderef really is only (functionally) used by `rustc_hir_analysis` and `rustc_hir_typeck`, so it probably should live there. Instead, implement a separate autoderef helper in `TypeErrCtxt` for the one use-case that goes against the ordering of the crate graph..

Prefer non-`[type error]` candidates during selection Fixes #102130 Fixes #106351 r? types note: Alternatively we could filter out error where-clauses during param-env construction? But we still need to filter out impls with errors during `match_impl`, I think.

2023-01-11Rollup merge of #106521 - oskgo:remove-E0280, r=jackh726Yuki Okushi-7/+11
remove E0280 After looking at #61137 I tried my hand at E0280. I'm unable to find a reasonable example that emits the error. There are a couple of old examples that compile with the current compiler ([#26217](https://github.com/rust-lang/rust/issues/26217), [#42114](https://github.com/rust-lang/rust/issues/42114), [#27113](https://github.com/rust-lang/rust/issues/27113)) and there is a [bug with chalk](https://github.com/rust-lang/rust/blob/b7cdb635c4b973572307ad288466fba64533369c/src/test/ui/chalkify/bugs/async.rs) that makes it emit the error, with a couple more chalk bugs on zulip. It seems like the error is supposed to be emitted from unfulfilled where bounds, of which two are related to borrow checking (error in where T: 'a or where 'a: 'b) and thus tend to emit errors like "lifetime may not live long enough" from borrow checking instead. The final case is with type equality constraints (where <T as Iterator>::Item == u32), which is unimplemented ([#20041](https://github.com/rust-lang/rust/issues/20041)). That such different problems are supposed to have the same error code also seems strange to me. Since the error seems to only be emitted when using chalk I propose to remove it and replace it with an ICE instead. A crater run might be warranted. Pinging `@jackh726` due to removal of chalk test that now ICEs.

2023-01-09Rollup merge of #106389 - compiler-errors:no-canonicalized, r=lcnrfee1-dead-41/+41
Simplify some canonical type alias names * delete the `Canonicalized<'tcx>` type alias in favor for `Canonical<'tcx>` * `CanonicalizedQueryResponse` -> `CanonicalQueryResponse` I don't particularly care about the latter, but it should be consistent. We could alternatively delete the first alias and rename the struct to `Canonicalized`, and then keep the name of `CanonicalizedQueryResponse` untouched.
2023-01-09Rollup merge of #105655 - RedDocMD:bug-105645, r=oli-obkfee1-dead-0/+7
Remove invalid case for mutable borrow suggestion If we have a call such as `foo(&mut buf)` and after reference collapsing the type is inferred as `&T` where-as the required type is `&mut T`, don't suggest `foo(&mut mut buf)`. This is wrong syntactically and the issue lies elsewhere, not in the borrow. Fixes #105645
2023-01-09Clean upkadmin-23/+9
Simplify match statement Add multiple tests - 1 test for checking `N + 1 + 1` does not unify with `N+1` - 2 tests for checking that a function that uses two parameters only returns the parameter that is actually used. - Check exact repeat predicates

2023-01-09Set !const_evaluatable if ambig. and not inferredkadmin-12/+10
This prevents an ICE due to a value not actually being evaluatable later.
2023-01-09Change based on commentskadmin-7/+26
Instead of just switching to a probe, check for different matches, and see how many there are. If one, unify it, otherwise return true and let it be unified later.
