* Fix Chalk environmentsFlorian Diebold2019-09-071-2/+2
| | | | | The clauses need to be wrapped in `FromEnv` clauses for elaboration (i.e. things like inferring `T: Clone` from `T: Copy`) to work correctly.
* Use traits from where clauses for method resolutionFlorian Diebold2019-09-071-11/+10
| | | | | E.g. if we have `T: some::Trait`, we can call methods from that trait without it needing to be in scope.
* Lower `Fn(X, Y) -> Z` pathsFlorian Diebold2019-09-071-8/+8

* Lower bounds on trait definition, and resolve assoc types from super traitsFlorian Diebold2019-09-071-5/+5

|
* Properly format `impl Trait<Type = Foo>` typesFlorian Diebold2019-09-031-4/+4
| | | | | | It's a bit complicated because we basically have to 'undo' the desugaring, and the result is very dependent on the specifics of the desugaring and will probably produce weird results otherwise.

* Handle impl/dyn Trait in method resolutionFlorian Diebold2019-08-221-30/+52
| | | | | | | | | | | | | When we have one of these, the `Trait` doesn't need to be in scope to call its methods. So we need to consider this when looking for method candidates. (Actually I think the same is true when we have a bound `T: some::Trait`, but we don't handle that yet). At the same time, since Chalk doesn't handle these types yet, add a small hack to skip Chalk in method resolution and just consider `impl Trait: Trait` always true. This is enough to e.g. get completions for `impl Trait`, but since we don't do any unification we won't infer the return type of e.g. `impl Into<i64>::into()`.
* Add `impl Trait` and `dyn Trait` typesFlorian Diebold2019-08-221-0/+120
| | | | | | | - refactor bounds handling in the AST a bit - add HIR for bounds - add `Ty::Dyn` and `Ty::Opaque` variants and lower `dyn Trait` / `impl Trait` syntax to them

|\ | | | | | | | | | | | | | | | | | | | | | | 1515: Trait environment r=matklad a=flodiebold This adds the environment, i.e. the set of `where` clauses in scope, when solving trait goals. That means that e.g. in ```rust fn foo<T: SomeTrait>(t: T) {} ``` , we are able to complete methods of `SomeTrait` on the `t`. This affects the trait APIs quite a bit (since every method that needs to be able to solve for some trait needs to get this environment somehow), so I thought I'd do it rather sooner than later ;) Co-authored-by: Florian Diebold <[email protected]>

| |
| * Start handling environment in trait resolutionFlorian Diebold2019-07-081-0/+60
| | | | | | | | | | I.e. if we are inside a function with some where clauses, we assume these where clauses hold.

* Add trait obligations for where clauses when calling functions/methodsFlorian Diebold2019-07-061-21/+113
| | | | | E.g. if we call `foo<T: Into<u32>>(x)`, that adds an obligation that `x: Into<u32>`, etc.

| | | | | | This wasn't a right decision in the first place, the feature flag was broken in the last rustfmt release, and syntax highlighting of imports is more important anyway
