Avoid describing a method as 'not found' when bounds are unsatisfied Fixes #76267 When there is a single applicable method candidate, but its trait bounds are not satisfied, we avoid saying that the method is "not found". Insted, we update the error message to directly mention which bounds are not satisfied, rather than mentioning them in a note. 2020-09-26 16:20:14 -05:00			error[E0599]: the method `is_subset` exists for reference `&HashSet<T>`, but its trait bounds were not satisfied

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 02:40:56 -05:00			`T: Eq`
