Reword `rustc_on_unimplemented` errors for `Iterator` - Detect one element array of `Range` type, which is potentially a typo: `for _ in [0..10] {}` where iterating between `0` and `10` was intended. (#23141) - Suggest `.bytes()` and `.chars()` for `String`. - Suggest borrowing or `.iter()` on arrays (#36391) - Suggest using range literal when iterating on integers (#34353) - Do not suggest `.iter()` by default (#50773, #46806) 2018-10-09 20:53:53 -05:00			error[E0277]: `()` is not an iterator

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 02:40:56 -05:00			= help: the trait `Iterator` is not implemented for `()`
