Ensure that the return type of a function is Sized While no real rvalue of an unsized type can exist, a diverging function can still "return" a value of such a type, which causes an ICE. Fixes #18107. 2014-10-18 20:12:02 +00:00

Suggest `-> impl Trait` and `-> Box<dyn Trait>` on fn that doesn't return During development, a function could have a return type set that is a bare trait object by accident. We already suggest using either a boxed trait object or `impl Trait` if the return paths will allow it. We now do so too when there are no return paths or they all resolve to `!`. We still don't handle cases where the trait object is not the entirety of the return type gracefully. 2020-04-10 17:19:47 +00:00			`//~^ ERROR return type cannot have an unboxed trait object`
