Delegate for dispatching a CodeExecutor call.
A utility trait for building an RPC extension given a
This is useful since at service definition time we don’t know whether the
specific interface where the RPC extension will be exposed is safe or not.
This trait allows us to lazily build the RPC extension whenever we bind the
service to an interface.
