* Make type walking infrastructure a bit nicerFlorian Diebold2019-09-038-133/+132
| | | | | If/when we switch to using Chalk's Ty, we'll need to replace this by its `Fold` trait, but I didn't want to import the whole thing just yet.
* Properly format `impl Trait<Type = Foo>` typesFlorian Diebold2019-09-032-23/+97
| | | | | | 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 Diebold2019-08-223-32/+79
| | | | | | | | | | | | | 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 Diebold2019-08-226-41/+339
| | | | | | | - 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

* Introduce separate hir::BinaryOpAleksey Kladov2019-08-173-69/+96
| | | | | Unlike ast::BinOp, it has significantly more structure to it, so it's easier to, say, handle all assignment-like operations in the same way.
