Functions

func NewPublisher 

func NewPublisher(topic string, conn *grpc.ClientConn) pubsub.Publisher

NewPublisher returns an implementation of pubsub.Publisher from the given grpc connection. This is a convenience in case you want to operate with go channels instead of interacting with the client directly

func NewSubscriber 

func NewSubscriber(topic, subscriptionID string, conn *grpc.ClientConn) pubsub.Subscriber

NewSubscriber returns an implementation of pubsub.Subscriber from the given grpc connection. This is a convenience in case you want to operate with go channels instead of interacting with the client directly

func RegisterPubSubServer 

func RegisterPubSubServer(s *grpc1.Server, srv PubSubServer)
