error[E0038]: the trait `AsyncTrait` is not dyn compatible
  --> $DIR/mut-is-pointer-like.rs:35:29

LL |         let x: Pin<&mut dyn AsyncTrait<Output = ()>> = f;
   |                             ^^^^^^^^^^^^^^^^^^^^^^^ `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: Pin<&mut Self>) -> Self::Output;
   |              ^^^^^^^^^^^^^^ ...because method `async_dispatch` is `async`
   = help: consider moving `async_dispatch` to another trait
