A simple set of io-uring bindings in Haskell. See Main.hs for an example on how to use it. The example code can be run with cabal run.
Since the io_uring interface was only added to the Linux kernel in version 5.1 (released around May 2019) so it's possible that you are running a kernel version that supports it. From the command line, uname -r will tell you the kernel version of your system.
It is NOT advised to cabal install --lib this repo to get the libraries installed as non-hidden modules. Part of the bindings include C-- code that prevents the GHCi bytecode interpreter from even starting up.
