2021-09-16Point at call span that introduced obligation for the argEsteban Kuber-5/+15
2021-09-16Point at argument instead of call for their obligationsEsteban Kuber-34/+3
When an obligation is introduced by a specific `fn` argument, point at the argument instead of the `fn` call if the obligation fails to be fulfilled.

2021-04-03Remove redundant `ignore-tidy-linelength` annotationsSimon Jakobi-3/+1
This is step 2 towards fixing #77548. In the codegen and codegen-units test suites, the `//` comment markers were kept in order not to affect any source locations. This is because these tests cannot be automatically `--bless`ed.

2020-09-02pretty: trim paths of unique symbolsDan Aloni-35/+35
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.

2019-10-15Use structured suggestion for restricting boundsEsteban Küber-8/+12
When a trait bound is not met and restricting a type parameter would make the restriction hold, use a structured suggestion pointing at an appropriate place (type param in param list or `where` clause). Account for opaque parameters where instead of suggesting extending the `where` clause, we suggest appending the new restriction: `fn foo(impl Trait + UnmetTrait)`.
