Functions ¶

func MessageID ¶

func MessageID(atts msg.Attributes) string

MessageID returns the pub/sub ID of the original message.

func MessagePublishTime ¶

func MessagePublishTime(atts msg.Attributes) time.Time

MessagePublishTime returns the pub/sub publish time of the original message.

func NewServer ¶

func NewServer(ctx context.Context, projectID, subID, topicID string) (msg.Server, error)

NewServer returns a server implementation for Google's Cloud Pub/Sub.

Serve will only receive messages currently in the subscription and then exit. This is currently a limitation in the SDK for Cloud Pub/Sub Pull model. In the future Serve may instead iterate and add a sleep to emulate more of a Push model or support an HTTPS endpoint to use Pub/Sub's push.

Types ¶

type Client ¶

type Client interface {
	Topic(context.Context, string) (msg.Topic, error)
}

Client represents a concrete implementation of a pubsub publisher client.

func NewClient ¶

func NewClient(ctx context.Context, projectID string) (Client, error)

NewClient returns a new instance of a pubsub Client for a given gcloud project.
