2020-09-09Rollup merge of #75984 - kornelski:typeormodule, r=matthewjasperTyler Mandry-4/+4
Improve unresolved use error message "use of undeclared type or module `foo`" doesn't mention that it could be a crate. This error can happen when users forget to add a dependency to `Cargo.toml`, so I think it's important to mention that it could be a missing crate. I've used a heuristic based on Rust's naming conventions. It complains about an unknown type if the ident starts with an upper-case letter, and crate or module otherwise. It seems to work very well. The expanded error help covers both an unknown type and a missing crate case.

2020-09-02pretty: trim paths of unique symbolsDan Aloni-122/+122
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.

2020-06-19Rollup merge of #71420 - RalfJung:specialization-incomplete, r=matthewjasperManish Goregaokar-5/+34
Specialization is unsound As discussed in https://github.com/rust-lang/rust/issues/31844#issuecomment-617013949, it might be a good idea to warn users of specialization that the feature they are using is unsound. I also expanded the "incomplete feature" warning to link the user to the tracking issue.
