| error[E0038]: the trait `Trait` is not dyn compatible |

| 12 | let _: &dyn Trait; |
| | ^^^^^^^^^^ `Trait` is not dyn compatible |
| | |
| note: for a trait to be dyn compatible it needs to allow building a vtable |

| 1 | pub trait Trait { |
| | ----- this trait is not dyn compatible... |
| 2 | async fn method(&self); |
| | ^^^^^^ ...because method `method` is `async` |
| = help: consider moving `method` to another trait |
| = help: only type `Struct` implements `Trait` within this crate; consider using it directly instead. |
| = note: `Trait` may 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 |
