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.

I didn't mention tokio's io_uring because, as far as I understand, it is unmaintained. I vaguely recall a conversation in which someone (a contributor?) was claiming that it was not possible to implement most of the features of tokio on io_uring due to conflicting models. [source needed], obviously.

I will admit the very existence of glommio or monoio had entirely slipped my mind. I'll probably need to add a few paragraphs about thread-per-core runtimes. Thanks!
