error: the trait `X` cannot be made into an object

= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
|

= note: for more information, see issue #51443 <https://github.com/rust-lang/rust/issues/51443>
|
|
note: for a trait to be "object safe" it needs to allow building a vtable to allow the call to be resolvable dynamically; for more information visit <https://doc.rust-lang.org/reference/items/traits.html#object-safety>
