As a follow up to the previous entry, you can also include a function to return a casts array for a trait/concern that your eloquent model is using.

trait HasUuid  
{
    public function getHasUuidCasts()
    {
        if(config('uuid.binary_format')) {
            return ['uuid' => 'uuid'];
        }

        return [];
    }

    //
}

Here is the trait that will enable this functionality on your eloquent models.

trait HasTraitsWithCasts  
{
    /**
     * Get the casts array.
     *
     * @return array
     */
    public function getCasts()
    {
        $class = static::class;

        foreach (class_uses_recursive($class) as $trait) {
            if (method_exists($class, $method = 'get'.class_basename($trait).'Casts')) {
                $this->casts = array_unique(array_merge($this->casts, $this->{$method}()));
            }
        }

        return parent::getCasts();
    }
}
