|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 982: Implement BindingMode for pattern matching. r=flodiebold a=mjkillough Implement `BindingMode` for pattern matching, so that types can be correctly inferred using match ergonomics. The binding mode defaults to `Move` (referred to as 'BindingMode::BindByValue` in rustc), and is updated by automatic dereferencing of the value being matched. Fixes #888. - [Binding modes in The Reference](https://doc.rust-lang.org/reference/patterns.html#binding-modes) - [`rustc` implementation](https://github.com/rust-lang/rust/blob/e17c48e2f21eefd59748e364234efc7037a3ec96/src/librustc_typeck/check/_match.rs#L77) (and [definition of `BindingMode`](https://github.com/rust-lang/rust/blob/e957ed9d10ec589bdd523b88b4b44c41b1ecf763/src/librustc/ty/binding.rs)) - [Match Ergonomics RFC](https://github.com/rust-lang/rfcs/blob/master/text/2005-match-ergonomics.md#binding-mode-rules) Co-authored-by: Michael Killough <[email protected]>

* Fix resolution of associated method calls across cratesFlorian Diebold2019-02-231-2/+39
| | | | | | I think it'll be better to make the path resolution the number of unresolved segments, not the first unresolved index; then this error could simply not have happened. But I'll do that separately.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | 866: Implement basic support for Associated Methods r=flodiebold a=vipentti This is my attempt at learning to understand how the type inference works by adding basic support for associated methods. Currently it does not resolve associated types or constants. The basic idea is that `Resolver::resolve_path` returns a new `PathResult` type, which has two variants, `FullyResolved` and `PartiallyResolved`, fully resolved matches the previous behavior, where as `PartiallyResolved` contains the `PerNs<Resolution` in addition to a `segment_index` which contains the index of the segment which we failed to resolve. This index can then be used to continue inference in `infer_path_expr` using the `Type` we managed to resolve. This changes some of the previous apis, so looking for feedback and suggestions. This should enable fixing #832 Co-authored-by: Ville Penttinen <[email protected]>

| * Implement basic support for Associated Methods and ConstantsVille Penttinen2019-02-216-0/+222
| | | | | | | | | | | | | | This is done in `infer_path_expr`. When `Resolver::resolve_path` returns `PartiallyResolved`, we use the returned `Resolution` together with the given `segment_index` to check if we can find something matching the segment at segment_index in the impls for that particular type.
