class MyNexusService:
    my_operation: nexusrpc.Operation[MyInput, MyOutput]

service: ServiceDefinition | None = ¶

The service that contains this operation.

nexusrpc.service and nexusrpc.handler.service_handler set this value. Each decorated class has its own operations. Thus, when a child service inherits an operation from a parent service, the operation reports the child service. The value is None when the operation is not part of a decorated class.
