* Fix shifting of binders in FnPointerFlorian Diebold2021-04-051-2/+4
| | | | | | | | | - don't shift in/out for Chalk mapping (we want to have the same binders now) - do shift in when creating the signature for a closure (though it shouldn't matter much) - do shift in when lowering a `fn()` type - correctly deal with the implied binder in TypeWalk
* Align FnPointer with ChalkFlorian Diebold2021-04-052-7/+7

|
* Move things in hir_ty into submodulesFlorian Diebold2021-04-044-9/+5
| | | | | - all the types that will be replaced by Chalk go to `types` - `TypeWalk` impls go to `walk`

|
* Rename Ty::interned to Ty::kindFlorian Diebold2021-04-035-19/+19
| | | | ... since that's the actual method on Chalk side that matches the signature.
* Introduce `GenericArg` like in ChalkFlorian Diebold2021-04-035-46/+58
| | | | | | | Plus some more adaptations to Substitution. Lots of `assert_ty_ref` that we should revisit when introducing lifetime/const parameters.
* Don't recheck obligations if we have learned nothing newFlorian Diebold2021-04-013-5/+11
| | | | | | | | | | 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).
* internal: ensure that runaway type-inference doesn't block the main loopAleksey Kladov2021-03-291-0/+2
| | | | | | We have a bug where type-checking `per_query_memory_usage` takes a couple of seconds. It also reveals another bug: our type inference is not cancellable.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 8201: Fix recursive macro statements expansion r=edwin0cheng a=edwin0cheng This PR attempts to properly handle macro statement expansion by implementing the following: 1. Merge macro expanded statements to parent scope statements. 2. Add a new hir `Expr::MacroStmts` for handle tail expression infer. PS : The scope of macro expanded statements are so strange that it took more time than I thought to understand and implement it :( Fixes #8171 Co-authored-by: Edwin Cheng <[email protected]>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 7907: Autoderef with visibility r=cynecx a=cynecx Fixes https://github.com/rust-analyzer/rust-analyzer/issues/7841. I am not sure about the general approach here. Right now this simply tries to check whether the autoderef candidate is reachable from the current module. ~~However this doesn't exactly work with traits (see the `tests::macros::infer_derive_clone_in_core` test, which fails right now).~~ see comment below Refs: - `rustc_typeck` checking fields: https://github.com/rust-lang/rust/blob/66ec64ccf31883cd2c28d045912a76179c0c6ed2/compiler/rustc_typeck/src/check/expr.rs#L1610 r? @flodiebold Co-authored-by: cynecx <[email protected]>

|\ \ | | | | | | | | | | | | | | | | | | | | | 8139: Align `Canonical` and `InEnvironment` with the Chalk versions r=flodiebold a=flodiebold Co-authored-by: Florian Diebold <[email protected]>
| * | Align InEnvironment with ChalkFlorian Diebold2021-03-213-16/+13
| | | | | | | | | | | | | | | | | | 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.
| * | Align Canonical more with Chalk's versionFlorian Diebold2021-03-211-14/+30
| | | | | | | | | | | | In particular, use chalk_ir::CanonicalVarKinds.

| | | | | | | | | | | | | | | Still far too much binder skipping going on; I find it hard to imagine this is all correct, but the tests pass.
