Avoid extra error for type mismatches in patterns When a type error has already occurred, don't call ty::subst, which may ICE due to the mismatch in the number of type params involved. I'm deeming this too small to review. Closes #3680 2012-12-11 21:10:30 +00:00			`fn main() {`

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			//~\| expected enum `Option<_>`
path trimming: ignore type aliases 2021-01-28 16:01:36 +00:00			//~\| found enum `Result<_, _>`
Modify primary span label for E0308 The previous output was unintuitive to users. 2023-01-03 02:00:33 +00:00			//~\| expected `Option<_>`, found `Result<_, _>`
