Dan Aloni	07e7823c01	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 22:26:37 +03:00

David Wood	0f2bd56b29	lint/ty: move fns to avoid abstraction violation ... This commit moves `transparent_newtype_field` and `is_zst` to `LateContext` where they are used, rather than being on the `VariantDef` and `TyS` types. Signed-off-by: David Wood <david@davidtw.co>	2020-08-30 18:57:46 +01:00
