Async code is simpler because you're implicitly holding a lock on the CPU. That's also why you should stay away from it: it increases latency. Especially since Rust is about speed and responsiveness. In general, async programming in Rust makes little sense.
I love Rust. But I’m 100% convinced Rust chose the wrong tradeoffs with their async model. Just give me green threads and use malloc to grow the stack. It’s fine. That would have been better imho.
