Type Alias DynExecutor 

pub type DynExecutor = dyn SomeExecutor<ExecutorNotifier = Infallible>;

The appropriate type for a dynamically-dispatched executor.

This type alias provides a convenient way to work with trait objects for executors when the concrete type isn’t known at compile time.

Example

fn store_executor(exec: Box<DynExecutor>) {
    // Can store and use the executor dynamically
}
