Types

type AcknowledgeRequest 

type AcknowledgeRequest struct {
	// AckId: The acknowledgment ID for the message being acknowledged. This
	// was returned by the Pub/Sub system in the Pull response.
	AckId []string `json:"ackId,omitempty"`

type Label 

type Label struct {
	// Key: The key of a label is a syntactically valid URL (as per RFC
	// 1738) with the "scheme" and initial slashes omitted and with the
	// additional restrictions noted below. Each key should be globally
	// unique. The "host" portion is called the "namespace" and is not
	// necessarily resolvable to a network endpoint. Instead, the namespace
	// indicates what system or entity defines the semantics of the label.
	// Namespaces do not restrict the set of objects to which a label may be
	// associated.
	//
	// Keys are defined by the following grammar:
	//
	// key = hostname "/" kpath kpath = ksegment *[ "/" ksegment ] ksegment
	// = alphadigit | *[ alphadigit | "-" | "_" | "." ]
	//
	// where "hostname" and "alphadigit" are defined as in RFC
	// 1738.

	// Ack, but it is possible that the message has been already delivered
	// again. Multiple Acks to the message are allowed and will
	// succeed.
	//
	// For push delivery, this value is used to set the request timeout for
	// the call to the push endpoint.
	//
	// For pull delivery, this value is used as the initial value for the
	// Ack deadline. It may be overridden for a specific pull request
	// (message) with ModifyAckDeadline. While a message is outstanding
	// (i.e. it has been delivered to a pull subscriber and the subscriber

This is only used for messages received via pull.

func (*SubscriptionsService) Create

Create: Creates a subscription on a given topic for a given subscriber. If the subscription already exists, returns ALREADY_EXISTS. If the corresponding topic doesn't exist, returns NOT_FOUND.

If the name is not provided in the request, the server will assign a random name for this subscription on the same project as the topic.

func (*SubscriptionsService) Delete

Messages will be accumulated for delivery even if no push configuration is defined or while the configuration is modified.

func (*SubscriptionsService) Pull 

func (r *SubscriptionsService) Pull(pullrequest *PullRequest) *SubscriptionsPullCall

Pull: Pulls a single message from the server. If return_immediately is true, and no messages are available in the subscription, this method returns FAILED_PRECONDITION. The system is free to return an UNAVAILABLE error if no messages are available in a reasonable amount of time (to reduce system load).

func (*SubscriptionsService) PullBatch 

func (r *SubscriptionsService) PullBatch(pullbatchrequest *PullBatchRequest) *SubscriptionsPullBatchCall

PullBatch: Pulls messages from the server. Returns an empty list if there are no messages available in the backlog. The system is free to return UNAVAILABLE if there are too many pull requests outstanding for the given subscription.
