* 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]>
| * Use environment for associated type normalization as wellFlorian Diebold2019-07-081-0/+19
| |
| * 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.
* allow rustfmt to reorder importsAleksey Kladov2019-07-041-7/+8
| | | | | | 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

* Use traits from prelude for method resolutionFlorian Diebold2019-05-121-0/+29
|
* Blacklist some traits from being considered in where clausesFlorian Diebold2019-05-121-6/+6
| | | | | | | For Send/Sync/Sized, we don't handle auto traits correctly yet and because they have a lot of impls, they can easily lead to slowdowns. In the case of Fn/FnMut/FnOnce, we don't parse the special Fn notation correctly yet and don't handle closures yet, so we are very unlikely to find an impl.
* Add support for inline boundsFlorian Diebold2019-05-111-0/+33
| | | | E.g. impl<T: Clone> Foo for T.
* Reduce Chalk max_size parameter, add test for slow caseFlorian Diebold2019-05-111-0/+29

* Handle Chalk conversion for FnDefFlorian Diebold2019-05-111-0/+13
|
* Handle resolution errors in where clausesFlorian Diebold2019-05-111-0/+15
| | | | | This is slightly hacky, but maybe more elegant than alternative solutions: We just use a hardcoded Chalk trait ID which we special-case to have no impls.

* Chalk integrationFlorian Diebold2019-05-041-1/+1
| | | | | - add proper canonicalization logic - add conversions from/to Chalk IR
* Introduced resolve_macro_call on resolverLenard Pratt2019-04-231-0/+26
| | | | | | changed to manual expansion fix for nested macros
* Add HIR for where clauses & ignore impls with where clauses in trait resolutionFlorian Diebold2019-04-211-0/+17
| | | | | This prevents any `impl<T> Trait for T where ...` from being treated as a blanket impl while we don't handle where clauses yet.
* Add a simple test for str method completionFlorian Diebold2019-04-201-0/+22

* Fix 1099Edwin Cheng2019-04-171-2/+61
|
* Refactor method candidate generation a bitFlorian Diebold2019-04-141-0/+65
| | | | | | This fixes the order in which candidates are chosen a bit (not completely though, as the ignored test demonstrates), and makes autoderef work with trait methods. As a side effect, this also makes completion of trait methods work :)
* More trait infrastructureFlorian Diebold2019-04-141-8/+43
| | | | | | | | | | - make it possible to get parent trait from method - add 'obligation' machinery for checking that a type implements a trait (and inferring facts about type variables from that) - handle type parameters of traits (to a certain degree) - improve the hacky implements check to cover enough cases to exercise the handling of traits with type parameters - basic canonicalization (will probably also be done by Chalk)
