If anything OOP might actually be detrimental to many game engine applications (in a modern computing context in regards to the kind of data layouts and implementation patterns it encourages), and traits and "traditional" OOP (if you exclude implementation inheritance, which is largely cursed anyways) are real close together anyways, I think Rust is a great fit specifically for game engines at least, for gameplay programming I'm not as certain but for anything where you're mostly managing essentially data pipelines that need to go very fast and be reliable and not crashy, Rust is a great fit.
