+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link StorageClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (storage.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 startResumableWrite to 30 seconds:
+ *
+ * <pre>{@code
+ * StorageSettings.Builder storageSettingsBuilder = StorageSettings.newBuilder();
+ * storageSettingsBuilder
+ *     .startResumableWriteSettings()
+ *     .setRetrySettings(
+ *         storageSettingsBuilder
+ *             .startResumableWriteSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * StorageSettings storageSettings = storageSettingsBuilder.build();
+ * }</pre>
