| * Fix #3373Florian Diebold2020-03-014-6/+45
| | | | | | | | | | | | | | 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 wrong handling of bare `dyn Trait` exposed by canonicalizer fixFlorian Diebold2020-02-221-1/+3
| | | | | The self type in the `dyn Trait` trait ref should always be ^0, but we didn't put that in there in the bare case.

* Fix handling of binders in canonicalizationFlorian Diebold2020-02-221-64/+35

|
* 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.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 3169: Show record field names in Enum completion r=flodiebold a=adamrk Adresses https://github.com/rust-analyzer/rust-analyzer/issues/2947. Previously the details shown when autocompleting an Enum variant would look like the variant was a tuple even if it was a record: ![2020-02-16-15:59:32_crop](https://user-images.githubusercontent.com/16367467/74607233-64f21980-50d7-11ea-99db-e973e29c71d7.png) This change will show the names of the fields for a record and use curly braces instead of parentheses: ![2020-02-16-15:33:00_crop](https://user-images.githubusercontent.com/16367467/74607251-8ce17d00-50d7-11ea-9d4d-38d198a4aec0.png) This required exposing the type `adt::StructKind` from `ra_hir` and adding a function ``` kind(self, db: &impl HirDatabase) -> StructKind ``` in the `impl` of `EnumVariant`. 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`.

* | Fix coercion of &T to itselfFlorian Diebold2020-02-162-0/+24
| | | | | | | | | | The autoderef coercion logic did not handle matching placeholders. This led to some type mismatches.
* | Extend analysis-stats a bitFlorian Diebold2020-02-151-0/+3
|/ | | | | | | | | | | | This adds some tools helpful when debugging nondeterminism in analysis-stats: - a `--randomize` option that analyses everything in random order - a `-vv` option that prints even more detail Also add a debug log if Chalk fuel is exhausted (which would be a source of nondeterminism, but didn't happen in my tests). I found one source of nondeterminism (rust-lang/chalk#331), but there are still other cases remaining.
