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

| ^^^^^^^^^^ `AsyncTrait` is not dyn compatible
|
|
|
|
|
note: for a trait to be dyn compatible it needs to allow building a vtable

LL | async fn async_dispatch(&self);
|
|
| ^^^^^^^^^^^^^^ ...because method `async_dispatch` is `async`
|
|
= help: consider moving `async_dispatch` to another trait
|
|
= help: only type `&'static str` implements `AsyncTrait`; consider using it directly instead.
