> In practice, things are a bit more complicated. In fact, I don’t know of any async/await embedding on top of io_uring in any language yet, because it doesn’t quite match this model. But generally, that’s the idea.

Glommio and monoio are async runtimes in rust on top of io_uring and Tokio has an optional io_uring backend. Does that not count? This is such a well researched article that this kind of statement makes me think I’m missing something - surprising the author would get this wrong.

As far as I know those libraries only implement basic things. They don't use registered buffers, registered file descriptors, etc, and don't implement advanced features like chained operations.

They are async libraries built on io-uring though. Other mainstream async libraries also don’t go as deep as possible on epoll or other things either afaik
