it was not suitable for real-time systems few years ago, they undefaulted the gc few patches ago (in favor of orc), however even using the same rust's memory management, you're gonna have 100% of the heap objects to be traced; rust ownership model allows you to avoid tracing (such as arc) when they are not strictly necessary. that said i really don't like rust and all its approaches, i strictly recommend to have a look at nim;
