How is it a code smell? I'm pretty sure interior mutability is a well established design pattern. I'm not really familiar with the pattern you're describing using Ref/RefMut wrapping, could you show me what you mean?

Yeah I didn't want to pour a bunch of time into wrangling borrow checker stuff for a small code snippet.

Finally got around to writing the code, here's the link to the Rust playground with it. I was too lazy to do the unsafe stuff, but where I call clone in the deny and accept functions are where you'd rewrite and do unsafe magic to swap out elements without the clone overhead.

I also tried to implement a take function (like in Option) for the Allowable enum. Transferring ownership like with take would keep you in safe land and get what you want done.

Keep in mind I am not a game dev. I don't do cache optimizations. I have no idea how this code would function in a game context, but this is just my first idea for implementation of what you asked.

I don't think you need a mutex for this situation.

What are the conditions for T to be accessed? You could potentially wrap each instance of T in an enum that has two states, Allow and Deny, where if you encounter a Deny you just don't access that one. If you have a slice of this enum where each enum owns T, you can always just swap out a Deny for an Allow or vice versa depending on how you want to do it. If you go this route, you might want to make a struct that owns the vector mutably, can return an immutable borrow to the slice, and change permissions on the slice. Now that I'm thinking about it, you can also implement a gets function on the struct that would return a Result depending on whether it was an allow or a deny. I don't think you'd need unsafe with this.

The solution mostly depends on the context surrounding how you're managing what can access T and at what time. I can see the solution I proposed not working if you need more specific permissions than allow or deny, or if the permissions are based on the caller.

Edit: I'm going to come back in a few hours and write code about what I mean in the first paragraph.

And all the moderations should be down using optimized agentic workflows.

Holy fuck I forgot about this copypasta

Tell me what you think! Its my first real project.

Yeah I didn't want to just post it to some random platform, plus I wanted to contribute in some way so giving a torrenting guide seemed like the perfect choice!

Good bot

It's crazy how its robust to boxes being taken offline during training. That's honestly magic.

Does PIA stand for something?

Yeah me too, but I wanted to write a guide on torrenting and have a reason for people to potentially see my music in the process!
