Update ui test suite to use dyn 2019-05-28 14:46:13 -04:00			`&dyn Array;`
Refactor dyn-compatibility error and suggestions This CL makes a number of small changes to dyn compatibility errors: - "object safety" has been renamed to "dyn-compatibility" throughout - "Convert to enum" suggestions are no longer generated when there exists a type-generic impl of the trait or an impl for `dyn OtherTrait` - Several error messages are reorganized for user readability Additionally, the dyn compatibility error creation code has been split out into functions. cc #132713 cc #133267 2024-11-20 14:19:36 -08:00			//~^ ERROR `Array` is not dyn compatible
