Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit pkg.go.dev/cloud.google.com/go.

The server responds with a PublishResponse for each PublishRequest sent by the client, in the same order that the requests were sent. Note that multiple PublishRequests can be in flight simultaneously, but they will be processed by the server in the order that they are sent by the client on a given stream.

Example

Code:play  

package main

	c, err := pubsublite.NewPublisherClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	stream, err := c.Publish(ctx)
	if err != nil {
		// TODO: Handle error.
	}

		reqs := []*pubsublitepb.PublishRequest{
			// TODO: Create requests.
		}
		for _, req := range reqs {
			if err := stream.Send(req); err != nil {
				// TODO: Handle error.
			}
