The raw io_uring interface, once you ignore the boilerplate initialization code, is actually a super-simple interface to use. liburing is itself only a very thin wrapper on top of io_uring. I feel that if you ever used io_uring, after a while you'll end up with a bunch of convenience functions. liburing looks more like a collection of those functions to me today.

One place where a slightly high-level interface is provided by liburing is in the function io_uring_submit(). It determines among other things if there is a need to call the io_uring_enter() system call depending on whether you are in polling mode or not, for example. You can read more about it here:

Otherwise, at least at this time, liburing is a simple wrapper.
