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			error[E0277]: `Rc<RefCell<A>>` cannot be sent between threads safely
Remove even more box syntax uses from src/test Prior work, notably 6550021124451628b1efc60c59284465b109e3aa from #88316 has removed box syntax from most of the testsuite. However, some tests were left out. This commit removes box_syntax uses from more locations in src/test. Some tests that are very box syntax specific are not being migrated. 2022-07-06 21:36:10 -05:00			`--> $DIR/issue-7013.rs:24:19`
