    Just cut rio 0.5! It's a pure-rust misuse-resistant io_uring library. io_uring will change everything about IO. The goldrush has started but folks don't realize it yet. #rustlang lifetimes+RAII tricks ensure safety. go measure the o_direct example vs what you currently use :] https://twitter.com/sadisticsystems/status/1213188697274888192 …pic.twitter.com/htOKHXBOEk

        TBO I had to read up on what the io_uring even is. Sounds pretty exciting. So do you think it's gonna be like what swiss tables are to hashmaps?

        This is way bigger. It's going to make things that need to use disk 3x faster. It addresses one of the biggest complaints about the linux kernel for my entire career: friction around real async file IO. It lets you dramatically reduce / eliminate syscalls for file & network IO.

        I am not exaggerating when I say it is going to change everything. Already for storage it's so easy to hit line speeds. I'm about to get linux 5.5 setup and post numbers about networking accept rates vs the other popular approaches, but I fully expect it to be a bloodbath.

        Very interesting. What are the short pros/cons of this vs IOU?

        iou is basically just a low-level unsafe binding to the C library. rio is pure rust, no need to compile and link against C, and it aims to prevent a lot of misuse by leveraging rust's lifetimes and RAII to make use-after-free of the buffers you feed io_uring impossible

        Completion implements Future, so you can use it with any async runtime. mio is just a thing that smacks epoll/kqueue/iocp as rio smacks io_uring. you can use rio easily without an async runtime as well, using wait() instead of .await. I donno if mio 0.7 can still be used alone

        what is up with the last line of that README? I assume/hope it's a forgotten leftover joke, but maybe not something to publicise officially in its present format, @rustlang
