I copied this exact same snippet and was going to comment the exact same thing.
Why choose Rust if you don’t care about maintainability and long term stability? Those are core values of the language!
The language choice was wrong from the start. C++ is king for games so if you care more about delivering features and fast prototyping why not go with that?
Maybe Rust is not a good language for rapid iteration in the game industry. And that’s ok I think.
