* Implement inline associated type boundsFlorian Diebold2020-04-132-6/+69
| | | | | | | Like `Iterator<Item: SomeTrait>`. 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 :)

|\ | | | | | | | | | | | | | | | | | | 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 Diebold2020-04-105-56/+297
|/ | | | | | | | | | 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.

| | | | | | | | | | | | | | The big change here is counting binders, not variables (https://github.com/rust-lang/chalk/pull/360). We have to adapt to the same scheme for our `Ty::Bound`. It's mostly fine though, even makes some things more clear.

* Macro patterns are not confused with expressions.Aleksey Kladov2020-04-031-2/+29
| | | | | | | | | | | We treat macro calls as expressions (there's appropriate Into impl), which causes problem if there's expresison and non-expression macro in the same node (like in the match arm). We fix this problem by nesting macor patterns into another node (the same way we nest path into PathExpr or PathPat). Ideally, we probably should add a similar nesting for macro expressions, but that needs some careful thinking about macros in blocks: `{ am_i_expression!() }`.
