// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
 * Settings class to configure an instance of {@link RegionsClient}.
 *
 * <p>The default instance has everything set to sensible defaults:
 *
 * <ul>
 *   <li>The default service address (compute.googleapis.com) and default port (443) are used.
 *   <li>Credentials are acquired automatically through Application Default Credentials.
 *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
 * </ul>
 *
 * <p>The builder of this class is recursive, so contained classes are themselves builders. When
 * build() is called, the tree of builders is called to create the complete settings object.
 *
 * <p>For example, to set the total timeout of get to 30 seconds:
 *
 * <pre>{@code
 * // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 * RegionsSettings.Builder regionsSettingsBuilder = RegionsSettings.newBuilder();
 * regionsSettingsBuilder
 *     .getSettings()
 *     .setRetrySettings(
 *         regionsSettingsBuilder
 *             .getSettings()
 *             .getRetrySettings()
 *             .toBuilder()
 *             .setTotalTimeout(Duration.ofSeconds(30))
 *             .build());
 * RegionsSettings regionsSettings = regionsSettingsBuilder.build();
 * }</pre>
