* 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.
* Fix #3373Florian Diebold2020-03-011-3/+10
| | | | | | | 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 Diebold2020-02-291-2/+19
| | | | | | | 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 #2467Florian Diebold2019-12-031-4/+4
| | | | | The stand-alone `unify` requires that the type doesn't contain any type variables. So we can't share the code here for now (without more refactoring)...

| | | | | | - impl Trait<Self> for S is allowed - impl Trait for S<Self> is an invalid cycle, but we can add cycle recovery for it in Salsa now
