// Package pubsub provides access to the Cloud Pub/Sub API.
//
// This package is DEPRECATED. Use package cloud.google.com/go/pubsub instead.
//
// For product documentation, see: https://cloud.google.com/pubsub/docs
//
// Creating a client
//
// Usage example:
//
//   import "google.golang.org/api/pubsub/v1"
//   ...
//   ctx := context.Background()
//   pubsubService, err := pubsub.NewService(ctx)
//
// In this example, Google Application Default Credentials are used for authentication.
//
// For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.
//
// Other authentication options
//
// By default, all available scopes (see "Constants") are used to authenticate. To restrict scopes, use option.WithScopes:
//
//   pubsubService, err := pubsub.NewService(ctx, option.WithScopes(pubsub.PubsubScope))
//
// To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey:
//
//   pubsubService, err := pubsub.NewService(ctx, option.WithAPIKey("AIza..."))
//
// To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource:
//
//   config := &oauth2.Config{...}
//   // ...
//   token, err := config.Exchange(ctx, ...)
//   pubsubService, err := pubsub.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))
//
// See https://godoc.org/google.golang.org/api/option/ for details on options.

// a single `role`. Members can be user accounts, service accounts,
// Google groups, and domains (such as G Suite). A `role` is a named
// list of permissions; each `role` can be an IAM predefined role or a
// user-created custom role. For some types of Google Cloud resources, a
// `binding` can also specify a `condition`, which is a logical
// expression that allows access to a resource only if the expression
// evaluates to `true`. A condition can add constraints based on
// attributes of the request, the resource, or both. To learn which
// resources support conditions in their IAM policies, see the [IAM
// documentation](https://cloud.google.com/iam/help/conditions/resource-p
// olicies). **JSON example:** { "bindings": [ { "role":
// "roles/resourcemanager.organizationAdmin", "members": [
// "user:mike@example.com", "group:admins@example.com",
// "domain:google.com",
// "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, {
