|\ | | | | | | | | | | | | | | 4023: Fix another crash from wrong binders r=matklad a=flodiebold Basically, if we had something like `dyn Trait<T>` (where `T` is a type parameter) in an impl we lowered that to `dyn Trait<^0.0>`, when it should be `dyn Trait<^1.0>` because the `dyn` introduces a new binder. With one type parameter, that's just wrong, with two, it'll lead to crashes. Co-authored-by: Florian Diebold <[email protected]>

This is an unstable feature, but it's used in the standard library e.g. in the definition of Flatten, so we can't get away with not implementing it :) (This is cherry-picked from my recursive solver branch, where it works better, but I did manage to write a test that works with the current Chalk solver as well...) 3967: Handle `Self::Type` in trait definitions when referring to own associated type r=matklad a=flodiebold It was implemented for other generic parameters for the trait, but not for `Self`.

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | 3938: fix missing match arm false positive r=flodiebold a=JoshMcguigan This fixes #3932 by skipping the missing match arm diagnostic in the case any of the match arms don't type check properly against the match expression. I think this is the appropriate behavior for this diagnostic, since `is_useful` relies on all match arms being well formed, and the case of a malformed match arm should probably be handled by a different diagnostic.

|\ | | | | | | | | | | | | | | | | | | | | | | 3905: add ellipsis field to hir pat record r=matklad a=JoshMcguigan This PR corrects a `fixme`, adding an `ellipsis` field to the hir `Pat::Record` type. It will also be unlock some useful follow on work for #3894. Additionally it adds a diagnostic for missing fields in record patterns. ~~Marking as a draft because I don't have any tests, and a small amount of manual testing on my branch from #3894 suggests it might *not* be working. Any thoughts on how I can best test this, or else pointers on where I might be going wrong?~~ Co-authored-by: Josh Mcguigan <[email protected]>

* | Implement Chalk's debug methods using TLSFlorian Diebold2020-04-104-56/+295
|/ | | | | | | | | | Chalk now panics if we don't implement these methods and run with CHALK_DEBUG, so I thought I'd try to implement them 'properly'. Sadly, it seems impossible to do without transmuting lifetimes somewhere. The problem is that we need a `&dyn HirDatabase` to get names etc., which we can't just put into TLS. I thought I could just use `scoped-tls`, but that doesn't support references to unsized types. So I put the `&dyn` into another struct and put the reference to *that* into the TLS, but I have to transmute the lifetime to 'static for that to work.
