Moaning aside, what is (if any?) the direct equivalent to single-threaded asyncio, like Python or node.js, in Rust? The thing I enjoy about async in Python is that it's very easy to write "thread"-safe code - you know exactly where you might give up execution context, and 90% of the time you have no need for mutexes and locks. But as this article complains, in Rust, it seems to be sync or multi-threaded.
