   * @param string $path

   *   The path to process, with a leading slash.

   * @param array $options

   *   An array of options such as would be passed to the generator's

   *   generateFromRoute() method.

   *   (optional) An associative array of additional options, with the following

   *   elements:

   *   - 'query': An array of query key/value-pairs (without any URL-encoding)

   *     to append to the URL.

   *   - 'fragment': A fragment identifier (named anchor) to append to the URL.

   *     Do not include the leading '#' character.

   *   - 'absolute': Defaults to FALSE. Whether to force the output to be an

   *     absolute link (beginning with http:). Useful for links that will be

   *     displayed outside the site, such as in an RSS feed.

   *   - 'language': An optional language object used to look up the alias

   *     for the URL. If $options['language'] is omitted, it defaults to the

   *     current language for the language type LanguageInterface::TYPE_URL.

   *   - 'https': Whether this URL should point to a secure location. If not

   *     defined, the current scheme is used, so the user stays on HTTP or HTTPS

   *     respectively. TRUE enforces HTTPS and FALSE enforces HTTP.

   *   - 'base_url': Only used internally by a path processor, for example, to

   *     modify the base URL when a language dependent URL requires so.

   *   - 'prefix': Only used internally, to modify the path when a language

   *     dependent URL requires so.

   *   - 'route': The route object for the given path. It will be set by

   *     \Drupal\Core\Routing\UrlGenerator::generateFromRoute().

   * @param \Symfony\Component\HttpFoundation\Request $request

   *   The HttpRequest object representing the current request.

   * @param \Drupal\Core\Render\BubbleableMetadata $bubbleable_metadata
