| * internal: move diagnostics to hirAleksey Kladov2021-05-251-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea here is to eventually get rid of `dyn Diagnostic` and `DiagnosticSink` infrastructure altogether, and just have a `enum hir::Diagnostic` instead. The problem with `dyn Diagnostic` is that it is defined in the lowest level of the stack (hir_expand), but is used by the highest level (ide). As a first step, we free hir_expand and hir_def from `dyn Diagnostic` and kick the can up to `hir_ty`, as an intermediate state. The plan is then to move DiagnosticSink similarly to the hir crate, and, as final third step, remove its usage from the ide. One currently unsolved problem is testing. You can notice that the test which checks precise diagnostic ranges, unresolved_import_in_use_tree, was moved to the ide layer. Logically, only IDE should have the infra to render a specific range. At the same time, the range is determined with the data produced in hir_def and hir crates, so this layering is rather unfortunate. Working on hir_def shouldn't require compiling `ide` for testing.

| | | | So as to not use `TyKind::Error` as "no expectation".

|
* Rework obligation handlingFlorian Diebold2021-05-211-69/+15
| | | | | | | | We can't do the easy hack that we did before anymore, where we kept track of whether any inference variables changed since the last time we rechecked obligations. Instead, we store the obligations in canonicalized form; that way we can easily check the inference variables to see whether they have changed since the goal was canonicalized.
* Make diverging type variables work againFlorian Diebold2021-05-211-0/+3
| | | | | Chalk doesn't know about the `diverging` flag, so we need to instead propagate it before fully resolving the variables.

|
* Don't recheck obligations if we have learned nothing newFlorian Diebold2021-04-011-3/+15
| | | | | | | | | | This is just the most trivial check: If no inference variables have been updated, and there are no new obligations, we can just skip trying to solve them again. We could be smarter about it, but this already helps quite a bit, and I don't want to touch this too much before we replace the inference table by Chalk's. Fixes #8263 (well, improves it quite a bit).

* Align InEnvironment with ChalkFlorian Diebold2021-03-211-1/+1
| | | | | | This in particular means storing a chalk_ir::Environment, not our TraitEnvironment. This makes InEnvironment not usable for Type, where we need to keep the full TraitEnvironment.
* Turn Obligation into something similar to chalk_ir::DomainGoalFlorian Diebold2021-03-201-6/+6
| | | | This includes starting to make use of Chalk's `Cast` trait.

|\ | | | | | | | | | | | | | | | | | | 8018: Make Ty wrap TyKind in an Arc r=flodiebold a=flodiebold ... to further move towards Chalk. This is a bit of a slowdown (218ginstr vs 213ginstr for inference on RA), even though it allows us to unwrap the Substs in `TyKind::Ref` etc.. Co-authored-by: Florian Diebold <[email protected]>
| * Make Ty wrap TyKind in an ArcFlorian Diebold2021-03-141-6/+24
| | | | | | | | | | | | | | | | ... like it will be in Chalk. We still keep `interned_mut` and `into_inner` methods that will probably not exist with Chalk. This worsens performance slightly (5ginstr inference on RA), but doesn't include other simplifications we can do yet.
