list method
Lists GatewaySecurityPolicyRules in a given project and location.
Request parameters:
parent - Required. The project, location and GatewaySecurityPolicy from
which the GatewaySecurityPolicyRules should be listed, specified in the
format
projects/{project}/locations/{location}/gatewaySecurityPolicies/{gatewaySecurityPolicy}.
Value must have pattern
^projects/\[^/\]+/locations/\[^/\]+/gatewaySecurityPolicies/\[^/\]+$.
pageSize - Maximum number of GatewaySecurityPolicyRules to return per
call.
pageToken - The value returned by the last
'ListGatewaySecurityPolicyRulesResponse' Indicates that this is a
continuation of a prior 'ListGatewaySecurityPolicyRules' call, and that
the system should return the next page of data.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListGatewaySecurityPolicyRulesResponse.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
Implementation
async.Future<ListGatewaySecurityPolicyRulesResponse> list(
  core.String parent, {
  core.int? pageSize,
  core.String? pageToken,
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if (pageSize != null) 'pageSize': ['${pageSize}'],
    if (pageToken != null) 'pageToken': [pageToken],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v1/' + core.Uri.encodeFull('$parent') + '/rules';
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return ListGatewaySecurityPolicyRulesResponse.fromJson(
    response_ as core.Map<core.String, core.dynamic>,
  );
