// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
 * Settings class to configure an instance of {@link LibraryServiceStub}.
 *
 * <p>The default instance has everything set to sensible defaults:
 *
 * <ul>
 *   <li>The default service address (library-example.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
 * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
 * of createShelf:
 *
 * <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
 * LibraryServiceStubSettings.Builder libraryServiceSettingsBuilder =

 *     .createShelfSettings()
 *     .setRetrySettings(

 *             .createShelfSettings()

 *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
 *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
 *             .setRetryDelayMultiplier(1.3)
