Annotation to declare an RSocket endpoint on an RSocket service interface. Supported for use as an RSocket requester via RSocketServiceProxyFactory, and as a responder by implementing the interface to handle requests.

The endpoint route is determined through the annotation attribute, and through the method arguments.

The annotation is supported at the type level to express a common route, to be inherited by all methods.

Supported method arguments:
