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 10:40:56 +03:00			error[E0277]: the trait bound `&[i8]: From<&[u8]>` is not satisfied

Remove detail from label/note that is already available in other note Remove the "which is required by `{root_obligation}`" post-script in "the trait `X` is not implemented for `Y`" explanation in E0277. This information is already conveyed in the notes explaining requirements, making it redundant while making the text (particularly in labels) harder to read. ``` error[E0277]: the trait bound `NotCopy: Copy` is not satisfied --> $DIR/wf-static-type.rs:10:13 \| LL \| static FOO: IsCopy<Option<NotCopy>> = IsCopy { t: None }; \| ^^^^^^^^^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `NotCopy` \| = note: required for `Option<NotCopy>` to implement `Copy` note: required by a bound in `IsCopy` --> $DIR/wf-static-type.rs:7:17 \| LL \| struct IsCopy<T:Copy> { t: T } \| ^^^^ required by this bound in `IsCopy` ``` vs the prior ``` error[E0277]: the trait bound `NotCopy: Copy` is not satisfied --> $DIR/wf-static-type.rs:10:13 \| LL \| static FOO: IsCopy<Option<NotCopy>> = IsCopy { t: None }; \| ^^^^^^^^^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `NotCopy`, which is required by `Option<NotCopy>: Copy` \| = note: required for `Option<NotCopy>` to implement `Copy` note: required by a bound in `IsCopy` --> $DIR/wf-static-type.rs:7:17 \| LL \| struct IsCopy<T:Copy> { t: T } \| ^^^^ required by this bound in `IsCopy` ``` 2024-10-24 21:14:17 +00:00			\| ^^^^ the trait `From<&[u8]>` is not implemented for `&[i8]`
