| error[E0038]: the trait `Trait` cannot be made into an object |

| 12 | let _: &dyn Trait; |
| | ^^^^^^^^^^ `Trait` cannot be made into an object |
| | |
| 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> |

| 1 | pub trait Trait { |
| | ----- this trait cannot be made into an object... |
| 2 | async fn method(&self); |
| | ^^^^^^ ...because method `method` is `async` |
| = help: consider moving `method` to another trait |
| = help: only type `Struct` is seen to implement the trait in this crate, consider using it directly instead |
| = note: `Trait` can be implemented in other crates; if you want to support your users passing their own types here, you can't refer to a specific type |
