ShardingRegistrationEvent

The ShardingRegistrationEvent module models the live notifications emitted by Sharding when the local runner registers an entity handler or singleton. Consumers can use these events to wait for registrations during startup, inspect which capabilities a runner made available, or assert registration behavior in tests.

      SingletonRegistered: (args: SingletonRegistered) => any;
    },
  >(
    cases: Cases,
  ): (
    value: ShardingRegistrationEvent,
  ) => Unify<ReturnType<Cases["EntityRegistered" | "SingletonRegistered"]>>;
