I'm actually vibe coding a game engine right now using a Hexagonal Architecture, and I ran into this exact same issue when trying to synchronize the feedback loop between the viewport and the editor. To be fair, I probably messed up the domain boundaries myself in the first place, but honestly, the AI-generated code wasn't very effective at solving it either

Game engines are one of the worst case scenarios for something like Rust as game heaps are simulations of the real world, so have lots of complex graph structures in them. Affine types work best for request/response oriented stuff where lifetimes are clearly bounded.

So, I am currently changing the language. Thank you for your kind advice
