It seems like render() must be provided by classes using this trait. How about adding it as abstract method to this trait?

    }

    public function __toString() : string
    {
        try
        {
            return $this->render();
        }
        catch (Throwable $e)
        {
            return sprintf(
                'Exception while rendering [%s]: %s',
                get_class($this),
                $e->getMessage()
            );
        }
    }
}
