Module io_uring 

High-level interface over Linux io_uring.

Aims to provide an easy-to-use interface, while making some Firecracker-specific simplifying assumptions. The crate does not currently aim at supporting all io_uring features and use cases. For example, it only works with pre-registered fds and read/write/fsync requests.

Requires at least kernel version 5.10.51. For more information on io_uring, refer to the man pages. This pdf is also very useful, though outdated at times.
