* internal: move diagnostics to hirAleksey Kladov2021-05-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Rework obligation handlingFlorian Diebold2021-05-211-1/+2
| | | | | | | | 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.

* Add more tests, refactor array lengths/consteval workJade2021-05-141-0/+1
| | | | | | | | | | | Fix #2922: add unknown length as a condition for a type having unknown. Incorporate reviews: * Extract some of the const evaluation workings into functions * Add fixmes on the hacks * Add tests for impls on specific array lengths (these work!!! 😁) * Add tests for const generics (indeed we don't support it yet)
* Add lowering of array lengths in typesJade2021-05-131-3/+6
| | | | | | | | | | | Now e.g. ```rust fn a(b: [u8; 2]) { } ``` will know about the length of b.
* Add basic support for array lengths in typesJade2021-05-111-2/+5
| | | | | | | | | | This recognizes `let a = [1u8, 2, 3]` as having type `[u8; 3]` instead of the previous `[u8; _]`. Byte strings and `[0u8; 2]` kinds of range array declarations are unsupported as before. I don't know why a bunch of our rustc tests had single quotes inside strings un-escaped by `UPDATE_EXPECT=1 cargo t`, but I don't think it's bad? Maybe something in a nightly?

* Reorganize hir_ty modulesFlorian Diebold2021-04-091-1/+6
| | | | | Chalk isn't really a 'traits' thing anymore, so it doesn't make sense to have all the Chalk-related stuff in submodules of `traits`.

* | Move `equals_ctor` to `TyExt`Florian Diebold2021-04-071-31/+1
|/ | | | | | I'd prefer getting rid of it, but it's used in the impl search and not super easy to replace there (I think ideally the impl search would do proper unification, but that's a bit more complicated).
* Remove Ty::substs{_mut}Florian Diebold2021-04-071-28/+0
| | | | | | Almost all uses actually only care about ADT substs, so it's better to be explicit. The methods were a bad abstraction anyway since they already didn't include the inner types of e.g. `TyKind::Ref` anymore.
