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 18:53:53 -07:00			//~^ ERROR `()` is not an iterator
