// Package admin is an auto-generated package for the
// Identity and Access Management (IAM) API.
//
// Manages identity and access control for Google Cloud Platform resources,
// including the creation of service accounts, which you can use to
// authenticate to Google and make API calls.
//
//	NOTE: This package is in beta. It is not stable, and may be subject to changes.
//
// # Example usage
//
// To get started with this package, create a client.
//
//	ctx := context.Background()
//	// This snippet has been automatically generated and should be regarded as a code template only.
//	// It will require modifications to work:
//	// - It may require correct/in-range values for request initialization.
//	// - It may require specifying regional endpoints when creating the service client as shown in:
//	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
//	c, err := admin.NewIamClient(ctx)
//	if err != nil {
//		// TODO: Handle error.
//	}
//	defer c.Close()
//
// The client will use your default application credentials. Clients should be reused instead of created as needed.
// The methods of Client are safe for concurrent use by multiple goroutines.
// The returned client must be Closed when it is done being used.
//
// # Using the Client
//
// The following is an example of making an API call with the newly created client.
//
//	ctx := context.Background()
//	// This snippet has been automatically generated and should be regarded as a code template only.
//	// It will require modifications to work:
//	// - It may require correct/in-range values for request initialization.
//	// - It may require specifying regional endpoints when creating the service client as shown in:
//	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
//	c, err := admin.NewIamClient(ctx)
//	if err != nil {
//		// TODO: Handle error.
//	}
//	defer c.Close()
//
//	req := &adminpb.ListServiceAccountsRequest{
//		// TODO: Fill request struct fields.
//		// See https://pkg.go.dev/google.golang.org/genproto/googleapis/iam/admin/v1#ListServiceAccountsRequest.
//	}
//	it := c.ListServiceAccounts(ctx, req)
//	for {
//		resp, err := it.Next()
//		if err == iterator.Done {
//			break
//		}
//		if err != nil {
//			// TODO: Handle error.
//		}
//		// TODO: Use resp.
//		_ = resp
//	}
//
// # Use of Context
//
// The ctx passed to NewIamClient 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.
//

// please visit https://pkg.go.dev/cloud.google.com/go.
