     * @param string $path
     *   The path to process, with a leading slash.
     * @param array $options
     *   (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
     *   (optional) Object to collect path processors' bubbleable metadata.
     *
     * @return string
     *   The processed path.
