How to organize array elements through attributes in laravel data ?

[deniskorbakov]

Example:

class StoreDTO extends Data
{
    /**
     * @param array<int, int> $messagesId
     * @param array<int, int> $chatsId
     */
    public function __construct(
        #[Sometimes, ArrayType]
        public ?MessageStoreDTO $message,
        #[ArrayType, Exists('messages', 'id'), Max(10)]
        public array $messagesId,
        #[ArrayType, Exists('chats', 'id'), Max(10)]
        public array $chatsId,
    ) {
    }

    /** @return array<string, mixed> */
    public static function rules(): array
    {
        return [
            'messagesId.*' => ['distinct:strict', 'int'],
            'chatsId.*'    => ['distinct:strict', 'int'],
        ];
    }
}

Can you tell me if there is an attribute in which we can specify the rules for the elements of the array ?
