public RenderCacheInterface::set(array &$elements, array $pre_bubbling_elements)
Caches the rendered output of a renderable array.
May be called by an implementation of \Drupal\Core\Render\RendererInterface while rendering, if the #cache property is set.
Parameters
array $elements: A renderable array.
array $pre_bubbling_elements: A renderable array corresponding to the state (in particular, the cacheability metadata) of $elements prior to the beginning of its rendering process, and therefore before any bubbling of child information has taken place. Only the #cache property is used by this function, so the caller may omit all other properties and children from this array.
Return value
bool|null Returns FALSE if no cache item could be created, NULL otherwise.
