Your "Game" class only has constructor method and running_game method. The "square_number" is in the Player class and it is available upon initialization.

In the code above, I have noticed that you are trying to call class method without initializing the object. For instance,

This error message...

You can just go with simple if-else on returned value. I am giving you an example with some minor logical improvements.

Does a card need to be able to mutate the cards in self? If you know that execute will not need access to cards, the easiest solution is to split App into further structs so you can better limit the access of the function.

Unless there is another layer to your program that interacts with App as a singular object, requiring everything be in a single struct to perform operations will likely only constrain your code. If possible it is better to split it into its core components so you can be more selective when sharing references and avoid needing to make so many fields pub.

Here is a rough example:

Player.h includes Game.h and Game.h includes Player.h. This is an infinite loop. There might be more, but that's just the first one I saw.

You should remove at least one of those includes to break the infinite loop. If you get errors when you do that, you might be able to fix them using a forward declaration that looks something like this:

Because you don't know where exactly CWD was when the user has executed chroot syscall. It could be at /home/test/john or /home/test/john/mydir and so on.

But when you do chdir("..") syscall for let's say 5 times here. In the first case, it will take back to you on root in 3 chdir and when you perform .. on the root directory it is ineffective read more.

Now in the second case, it will take you to the root directory in 4 chdir("..") syscalls. So again .. on the root directory is ineffective. Generally, exploits use 1000 chdirs just because they don't want to take any chance to miss the actual root directory. Here from "actual root directory" I mean working directory or CWD.

When you do chroot it doesn't change the working directory or cwd for kernel but only changes for the applications running inside it. That is why when you don't drop the privileges and perform double chroot in the already chrooted environment it breaks you out of the chroot jail. I have understood this working from this post. I hope you will too find it useful.

Here is one more resource for you to understand difference between CWD and ROOT directory: https://github.com/earthquake/chw00t#got-that-but-how-does-it-work.

You have to update your import to:

Answer instead of edit, since it is significant: A fix for the service crash is as follows.

Looks like you are trying to make common text command and not slash command, so instead of interaction.user.displayAvatarURL you need to use message.author.displayAvatarURL!
