I feel like Rust is getting there but AFAIK there isn&#x27;t support for an untyped arena allocator(just homogeneous arena allocator) which you need if you don&#x27;t want to be playing around with raw byte arrays to do Data Oriented Design.<p>I think that they&#x27;ll get there but it&#x27;s going to take a bit.<p>Also, I&#x27;m not aware of anything that has a wider set of compile targets(all the way to some larger uC up to web via emscripten).
