2019-04-02Rollup merge of #59166 - seanmonstar:trait-alias-import, r=alexregMazdak Farrokhzad-0/+44
resolve: collect trait aliases along with traits It seems trait aliases weren't being collected as `TraitCandidates` in resolve, this should change that. (I can't compile the full compiler locally, so relying on CI...) Fixes https://github.com/rust-lang/rust/issues/56485 r? @alexreg
2019-04-01Refactor async fn return type loweringTaylor Cramer-26/+81
async fn now lowers directly to an existential type declaration rather than reusing the `impl Trait` return type lowering. As part of this, it lowers all argument-position elided lifetimes using the in-band-lifetimes machinery, creating fresh parameter names for each of them, using each lifetime parameter as a generic argument to the generated existential type. This doesn't currently successfully allow multiple argument-position elided lifetimes since `existential type` doesn't yet support multiple lifetimes where neither outlive the other. This requires a separate fix.

2019-03-31Suggest using anonymous lifetime in `impl Trait` return without hacksEsteban Küber-14/+18
Fallback to `static_impl_trait` for nice error message by peeking at the return type and the lifetime type. Point at the return type instead of the return expr/stmt in NLL mode.

pnkfelix:issue-56327-skip-dyn-keyword-lint-under-macros, r=matthewjasper skip dyn keyword lint under macros This PR is following my own intuition that `rustfix` should never inject bugs into working code (even if that comes at the expense of it failing to fix things that will become bugs).

This commit removes the check that disallows the `#[non_exhaustive]` attribute from being placed on enum variants and removes the associated tests. Further, this commit lowers the visibility of enum variant constructors when the variant is marked as non-exhaustive.

2019-03-28Revise and generalize the macros-unlinted tests.Felix S. Klock II-2/+85
Review feedback asked for the test to be generalized to include macros 2.0; that generalization is dyn-2015-idents-in-decl-macros-unlinted.rs As a drive-by, I also decided to revise the test to make it clear *why* we cannot generally lint these cases. (I already had similar demonstrations in dyn-2015-edition-keyword-ident-lint.rs, but it does not hurt to try to emphasize matters.) I also added some commentary on the cases where we could choose to make the lint smarter, namely the situations where a macro is *definitely* using `dyn` as an identifier (because it is using it as a path component).
2019-03-28Revise test slightly so that `dyn` in macro invocation *must* be parsed as ↵Felix S. Klock II-4/+4
keyword in test. Back-story: After reflection this morning, I realized that the previous form of this test would allow the macro invocation to treat the `dyn` input as a raw-identifier rather than a keyword, and since the input was discarded by that version of the macro, the test would pass despite the detail that the input `dyn` should not have been parsed as a raw-identifier. This revision fixes that oversight, by actually *using* the macro input to construct a `Box<dyn Trait>` type.
