Rust is just the language they happened to be working in. If you read through the LLM generated garbage it becomes clear that io_uring isnt the problem, their code was just slop / bad.
It would have been more precise to say O_DIRECT instead of io_uring. The point of io_uring is to avoid syscall overhead. What they were after was actually managing a page cache on their own, and it turned out to be more complicated than they thought.
Yay, first article (for me!) that i actually click on because the title is interesting, and then it puts me off because it's LLM generated.
By the way, what does Rust have to do with their problem? Is Rust simply bad at io_uring? :)

That was hinted at in the summary for part 2, which i couldn't bring myself to click on.
But my interpretation is still more fun!

The article's subheadings suggest this is AI slop. Seeing a section titles "The Production Symptom" is a Claudism in itself.
production symptom? is this equivalent to "kidney disappointment"?
