     *
     * @param  \Illuminate\Database\Eloquent\Model  $model
     * @param  string  $key
     * @param  mixed  $value
     * @param  array  $attributes
     * @return mixed
     */
    public function increment($model, string $key, $value, array $attributes);

    /**

     * @param  string  $key
     * @param  mixed  $value
