Preparations and cleanup Diagnostics for struct path resolution errors in resolve and typeck are unified. Self type is treated as a type alias in few places (not reachable yet). Unsafe cell is seen in constants even through type aliases. All checks for struct paths in typeck work on type level. 2016-09-15 00:51:46 +03:00			`// issue #36286`

pretty: trim paths of unique symbols If a symbol name can only be imported from one place for a type, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path and print only the name. This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable anywhere. This adds a new '-Z trim-diagnostic-paths=false' option to control this feature. On the good path, with no diagnosis printed, we should try to avoid issuing this query, so we need to prevent trimmed_def_paths query on several cases. This change also relies on a previous commit that differentiates between `Debug` and `Display` on various rustc types, where the latter is trimmed and presented to the user and the former is not. 2020-09-02 10:40:56 +03:00			//~^ ERROR the trait bound `NoClone: Clone` is not satisfied
