error[E0378]: implementing the `DispatchFromDyn` trait requires multiple coercions

= note: the trait `DispatchFromDyn` may only be implemented for a coercion between structures with a single field being coerced
= note: currently, 2 fields need coercions: `_ptr` (`Box<T>` to `Box<U>`), `z` (`()` to `i32`)
