| | ^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| = 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> |
