Renders a resource response body.

During serialization, encoders and normalizers are able to explicitly bubble cacheability metadata via the 'cacheability' key-value pair in the received context. This bubbled cacheability metadata will be applied to the the response.

@todo Add test coverage for language negotiation contexts in https://www.drupal.org/node/2135829.

Parameters

\Symfony\Component\HttpFoundation\Request $request: The request object.

\Drupal\rest\ResourceResponseInterface $response: The response from the REST resource.

\Symfony\Component\Serializer\SerializerInterface $serializer: The serializer to use.

string|null $format: The response format, or NULL in case the response does not need a format.
