public interface RetryingExecutor<ResponseT>A retrying executor is responsible for the following operations:
- Creating first attempt RetryingFuture, which acts as a facade, hiding from client code the actual execution of scheduled retry attempts.
- Executing the actual Callable in a retriable context.
This interface is for internal/advanced use only.
