	CreateTopic            []gax.CallOption
	UpdateTopic            []gax.CallOption
	Publish                []gax.CallOption
	GetTopic               []gax.CallOption
	ListTopics             []gax.CallOption
	ListTopicSubscriptions []gax.CallOption
	DeleteTopic            []gax.CallOption
}

PublisherCallOptions contains the retry settings for each method of PublisherClient.

type PublisherClient

type PublisherClient struct {

	// The call options for this service.
	CallOptions *PublisherCallOptions
	// contains filtered or unexported fields
}

PublisherClient is a client for interacting with Google Cloud Pub/Sub API.

func NewPublisherClient

func NewPublisherClient(ctx context.Context, opts ...option.ClientOption) (*PublisherClient, error)

NewPublisherClient creates a new publisher client.

The service that an application uses to manipulate topics, and to send messages to a topic.

Example
ctx := context.Background()
c, err := pubsub.NewPublisherClient(ctx)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use client.
_ = c
Output:

func (*PublisherClient) Close

func (c *PublisherClient) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*PublisherClient) Connection

func (c *PublisherClient) Connection() *grpc.ClientConn

Connection returns the client's connection to the API service.

func (*PublisherClient) CreateTopic

func (c *PublisherClient) CreateTopic(ctx context.Context, req *pubsubpb.Topic, opts ...gax.CallOption) (*pubsubpb.Topic, error)

Existing subscriptions to this topic are not deleted, but their topic field is set to _deleted-topic_.

Example
ctx := context.Background()
c, err := pubsub.NewPublisherClient(ctx)
if err != nil {
	// TODO: Handle error.

Output:

func (*SubscriberClient) Acknowledge

func (c *SubscriberClient) Acknowledge(ctx context.Context, req *pubsubpb.AcknowledgeRequest, opts ...gax.CallOption) error

Acknowledge acknowledges the messages associated with the ack_ids in the AcknowledgeRequest. The Pub/Sub system can remove the relevant messages from the subscription.

Acknowledging a message whose ack deadline has expired may succeed, but such a message may be redelivered later. Acknowledging a message more than once will not result in an error.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &pubsubpb.AcknowledgeRequest{
	// TODO: Fill request struct fields.

func (*SubscriberClient) Connection

func (c *SubscriberClient) Connection() *grpc.ClientConn

Connection returns the client's connection to the API service.

func (*SubscriberClient) CreateSnapshot added in v0.8.0

CreateSnapshot creates a snapshot from the requested subscription. If the snapshot already exists, returns ALREADY_EXISTS. If the requested subscription doesn't exist, returns NOT_FOUND.

If the name is not provided in the request, the server will assign a random name for this snapshot on the same project as the subscription, conforming to the resource name format (at https://cloud.google.com/pubsub/docs/overview#names). The generated name is populated in the returned Snapshot object. Note that for REST API requests, you must specify a name in the request.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &pubsubpb.CreateSnapshotRequest{
	// TODO: Fill request struct fields.
}
resp, err := c.CreateSnapshot(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp
Output:

func (*SubscriberClient) CreateSubscription

func (c *SubscriberClient) CreateSubscription(ctx context.Context, req *pubsubpb.Subscription, opts ...gax.CallOption) (*pubsubpb.Subscription, error)

CreateSubscription creates a subscription to a given topic. 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, conforming to the resource name format (at https://cloud.google.com/pubsub/docs/overview#names). The generated name is populated in the returned Subscription object. Note that for REST API requests, you must specify a name in the request.

Example
ctx := context.Background()

if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp
Output:

func (*SubscriberClient) DeleteSnapshot added in v0.8.0

func (c *SubscriberClient) DeleteSnapshot(ctx context.Context, req *pubsubpb.DeleteSnapshotRequest, opts ...gax.CallOption) error

DeleteSnapshot removes an existing snapshot. All messages retained in the snapshot are immediately dropped. After a snapshot is deleted, a new one may be created with the same name, but the new one has no association with the old snapshot or its subscription, unless the same subscription is specified.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &pubsubpb.DeleteSnapshotRequest{
	// TODO: Fill request struct fields.
}
err = c.DeleteSnapshot(ctx, req)
if err != nil {
	// TODO: Handle error.
}
Output:

func (*SubscriberClient) DeleteSubscription

func (c *SubscriberClient) DeleteSubscription(ctx context.Context, req *pubsubpb.DeleteSubscriptionRequest, opts ...gax.CallOption) error

DeleteSubscription deletes an existing subscription. All messages retained in the subscription are immediately dropped. Calls to Pull after deletion will return NOT_FOUND. After a subscription is deleted, a new one may be created with the same name, but the new one has no association with the old subscription or its topic unless the same topic is specified.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &pubsubpb.DeleteSubscriptionRequest{
	// TODO: Fill request struct fields.
}
err = c.DeleteSubscription(ctx, req)
if err != nil {
	// TODO: Handle error.
}
Output:

func (*SubscriberClient) GetSubscription

GetSubscription gets the configuration details of a subscription.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &pubsubpb.GetSubscriptionRequest{
	// TODO: Fill request struct fields.

if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp
Output:

func (*SubscriberClient) ListSnapshots added in v0.8.0

ListSnapshots lists the existing snapshots.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &pubsubpb.ListSnapshotsRequest{
	// TODO: Fill request struct fields.
}

	_ = resp
}
Output:

func (*SubscriberClient) ModifyAckDeadline

func (c *SubscriberClient) ModifyAckDeadline(ctx context.Context, req *pubsubpb.ModifyAckDeadlineRequest, opts ...gax.CallOption) error

ModifyAckDeadline modifies the ack deadline for a specific message. This method is useful to indicate that more time is needed to process a message by the subscriber, or to make the message available for redelivery if the processing was interrupted. Note that this does not modify the subscription-level ackDeadlineSeconds used for subsequent messages.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &pubsubpb.ModifyAckDeadlineRequest{
	// TODO: Fill request struct fields.
}

if err != nil {
	// TODO: Handle error.
}
Output:

func (*SubscriberClient) ModifyPushConfig

func (c *SubscriberClient) ModifyPushConfig(ctx context.Context, req *pubsubpb.ModifyPushConfigRequest, opts ...gax.CallOption) error

ModifyPushConfig modifies the PushConfig for a specified subscription.

This may be used to change a push subscription to a pull one (signified by an empty PushConfig) or vice versa, or change the endpoint URL and other attributes of a push subscription. Messages will accumulate for delivery continuously through the call regardless of changes to the PushConfig.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &pubsubpb.ModifyPushConfigRequest{
	// TODO: Fill request struct fields.
}
err = c.ModifyPushConfig(ctx, req)
if err != nil {
	// TODO: Handle error.
}
Output:

func (*SubscriberClient) Pull

Pull pulls messages from the server. Returns an empty list if there are no messages available in the backlog. The server may return UNAVAILABLE if there are too many concurrent pull requests pending for the given subscription.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &pubsubpb.PullRequest{
	// TODO: Fill request struct fields.
}
resp, err := c.Pull(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp
Output:

func (*SubscriberClient) Seek added in v0.8.0

Seek seeks an existing subscription to a point in time or to a given snapshot, whichever is provided in the request.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &pubsubpb.SeekRequest{
	// TODO: Fill request struct fields.
}
resp, err := c.Seek(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp
Output:

func (*SubscriberClient) SetGoogleClientInfo

func (c *SubscriberClient) SetGoogleClientInfo(keyval ...string)

SetGoogleClientInfo sets the name and version of the application in the `x-goog-api-client` header passed on each request. Intended for use by Google-written clients.

func (*SubscriberClient) StreamingPull added in v0.7.0

StreamingPull (EXPERIMENTAL) StreamingPull is an experimental feature. This RPC will respond with UNIMPLEMENTED errors unless you have been invited to test this feature. Contact cloud-pubsub@google.com with any questions.

Establishes a stream with the server, which sends messages down to the client. The client streams acknowledgements and ack deadline modifications back to the server. The server will close the stream and return the status on any error. The server may close the stream with status OK to reassign server-side resources, in which case, the client should re-establish the stream. UNAVAILABLE may also be returned in the case of a transient error (e.g., a server restart). These should also be retried by the client. Flow control can be achieved by configuring the underlying RPC channel.

Example
ctx := context.Background()
c, err := pubsub.NewSubscriberClient(ctx)
if err != nil {
	// TODO: Handle error.
}
stream, err := c.StreamingPull(ctx)
if err != nil {
	// TODO: Handle error.
}
go func() {
	reqs := []*pubsubpb.StreamingPullRequest{
		// TODO: Create requests.
	}
	for _, req := range reqs {
		if err := stream.Send(req); err != nil {
			// TODO: Handle error.
		}
	}
	stream.CloseSend()
}()
for {
	resp, err := stream.Recv()
	if err == io.EOF {
		break
	}
	if err != nil {
		// TODO: handle error.
	}
	// TODO: Use resp.
