     *     will be used.
     *   - An array of display options. The following key/value pairs are allowed:
     *     - label: (string) Position of the label. The default 'field' theme
     *       implementation supports the values 'inline', 'above' and 'hidden'.

     *       also be used if the requested formatter is not available.
     *     - settings: (array) Settings specific to the formatter. Defaults to the
     *       formatter's default settings.
     *     - weight: (float) The weight to assign to the renderable element.
