+   * @param string[]|null $display_types
+   *   (optional) The types of the display this plugin can be used with.
+   *   For example the Feed display defines the type 'feed', so only rss style
+   *   and row plugins can be used in the views UI.
+   * @param string[] $base
+   *   The base tables on which this cache plugin can be used.
+   *   If no base table is specified the plugin can be used with all tables.

+   *   Whether the plugin should be not selectable in the UI.
+   *   If set to TRUE, you can still use it via the API in config files.
+   * @param class-string|null $deriver
+   *   (optional) The deriver class.
