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 07:40:56 +00:00			error[E0277]: `Rc<usize>` cannot be sent between threads safely

Greatly improve error reporting for futures and generators in `note_obligation_cause_code` Most futures don't go through this code path, because they're caught by `maybe_note_obligation_cause_for_async_await`. But all generators do, and `maybe_note` is imperfect and doesn't catch all futures. Improve the error message for those it misses. At some point, we may want to consider unifying this with the code for `maybe_note_async_await`, so that `async_await` notes all parent constraints, and `note_obligation` can point to yield points. But both functions are quite complicated, and it's not clear to me how to combine them; this seems like a good incremental improvement. 2022-06-19 18:59:36 +00:00			`note: required because it's used within this closure`
