|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1815: Support correct `$crate` expansion in macros r=uHOOCCOOHu a=uHOOCCOOHu This PR makes normal use cases of `$crate` from macros work as expected. It makes more macros from `std` work. Type inference works well with `panic`, `unimplemented`, `format`, and maybe more. Sadly that `vec![1, 2, 3]` still not works, but it is not longer an issue about macro.

* Refactor some moreFlorian Diebold2019-09-171-39/+61
| | | | | | Type-relative paths (`<T>::foo`) also need to work in type context, for example `<T>::Item` is legal. So rather than returning the type ref from the resolver function, just check it before.
* Refactor associated item resolution moreFlorian Diebold2019-09-171-71/+54
| | | | | When resolving an associated item in value namespace, use the `Ty` lowering code for the segments before the last instead of replicating it.

* start cleaning up the resolutionAleksey Kladov2019-09-121-35/+11
| | | | | | | Nameres related types, like `PerNs<Resolution>`, can represent unreasonable situations, like a local in a type namespace. We should clean this up, by requiring that call-site specifies the kind of resolution it expects.
