namespace gcs = ::google::cloud::storage;
using ::google::cloud::StatusOr;

  StatusOr<gcs::BucketMetadata> bucket_metadata =
      client.GetBucketMetadata(bucket_name, gcs::Fields("labels"));

  if (!bucket_metadata) {
    throw std::runtime_error(bucket_metadata.status().message());
  }

  if (bucket_metadata->labels().empty()) {
    std::cout << "The bucket " << bucket_name << " has no labels set.\n";
    return;
  }

  std::cout << "The labels for bucket " << bucket_name << " are:";
  for (auto const& kv : bucket_metadata->labels()) {
    std::cout << "\n  " << kv.first << ": " << kv.second;
  }
  std::cout << "\n";
}
