* Fix completion with a partially unknown typeFlorian Diebold2020-03-101-3/+25
| | | | | | | | | | | | | | To test whether the receiver type matches for the impl, we unify the given self type (in this case `HashSet<{unknown}>`) with the self type of the impl (`HashSet<?0>`), but if the given self type contains Unknowns, they won't be unified with the variables in those places. So we got a receiver type that was different from the expected one, and concluded the impl doesn't match. The fix is slightly hacky; if after the unification, our variables are still there, we make them fall back to Unknown. This does make some sense though, since we don't want to 'leak' the variables. Fixes #3547.

* Don't reuse the Chalk solverFlorian Diebold2020-03-062-92/+28
| | | | | This slows down analysis-stats a bit (~5% in my measurement), but improves incremental checking a lot because we can reuse trait solve results.
* Resolve `Self::AssocTy` in implsFlorian Diebold2020-03-063-38/+93
| | | | | | | | | | To do this we need to carry around the original resolution a bit, because `Self` gets resolved to the actual type immediately, but you're not allowed to write the equivalent type in a projection. (I tried just comparing the projection base type with the impl self type, but that seemed too dirty.) This is basically how rustc does it as well. Fixes #3249.

|\ \ | |/ |/| | | | | | | | | | | | | | | | | 3385: Fix #3373 r=matklad a=flodiebold Basically, we need to allow variables in the caller self type to unify with the impl's declared self type. That requires some more contortions in the variable handling. I'm looking forward to (hopefully) handling this in a cleaner way when we switch to Chalk's types and unification code.

* Do array unsizing for method receiversFlorian Diebold2020-02-292-2/+37
| | | | | | | It turns out rustc actually only unsizes array method receivers, so we don't need to do any trait solving for this (at least for now). Fixes #2670.

* Fix a common false-positive type mismatchFlorian Diebold2020-02-293-9/+71
| | | | | | | | | E.g. for `&{ some_string() }` in a context where a `&str` is expected, we reported a mismatch inside the block. The problem is that we're passing an expectation of `str` down, but the expectation is more of a hint in this case. There's a long comment in rustc about this, which I just copied. Also, fix reported location for type mismatches in macros.

* Fix handling of const patternsFlorian Diebold2020-02-212-2/+48
| | | | | | | | | E.g. in `match x { None => ... }`, `None` is a path pattern (resolving to the option variant), not a binding. To determine this, we need to try to resolve the name during lowering. This isn't too hard since we already need to resolve names for macro expansion anyway (though maybe a bit hacky). Fixes #1618.

There was also a previously existing function `is_unit(self, db: &impl HirDatabase) -> bool` for `EnumVariant` which I removed because it seemed redundant after adding `kind`.
