Implementation
async.Future<GetBackupIndexDownloadUrlResponse> getBackupIndexDownloadUrl(
  core.String backup, {
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'v1/' + core.Uri.encodeFull('$backup') + ':getBackupIndexDownloadUrl';
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return GetBackupIndexDownloadUrlResponse.fromJson(
      response_ as core.Map<core.String, core.dynamic>);
