error[E0277]: the size for values of type `dyn ToString` cannot be known at compilation time
--> $DIR/issue-58355.rs:5:14
|
LL | x = Some(Box::new(callback));
| ^^^^^^^^^^^^^^^^^^ doesn't have a size known at compile-time
|
= help: within `fn() -> dyn ToString`, the trait `Sized` is not implemented for `dyn ToString`
= note: required because it appears within the type `fn() -> dyn ToString`
= note: required for the cast from `fn() -> dyn ToString` to the object type `dyn Fn() -> (dyn ToString + 'static)`
error: aborting due to previous error
