## What it is
tokio-uring is a Rust library that provides an io_uring-backed runtime compatible with the Tokio ecosystem, exposing new resource types (starting with file and network operations) driven by Linux's io_uring interface. Any library that works with Tokio also works with tokio-uring, but I/O is submitted to and completed by the kernel via io_uring for high-performance asynchronous I/O.

## Use cases
- perform async file I/O with io_uring in Rust
- use io_uring with the Tokio async runtime
- high-performance non-blocking disk reads and writes on Linux
- reduce syscall and blocking overhead in async I/O-heavy servers
- run Tokio-compatible code with an io_uring driver
- build low-latency filesystem or network I/O in Rust

## When to choose
- you need maximum I/O performance on Linux and can require a recent kernel with io_uring support
- you are already in the Tokio ecosystem but want io_uring-backed filesystem or network resources
- you are building I/O-bound services (storage, proxies, servers) where async file operations are a bottleneck

## When to avoid
- you need portability to macOS, Windows, or BSD since io_uring is Linux-only
- you must support older kernels, as very recent kernel versions are required
- you need a fully mature, broad API surface - the project focuses on filesystem and network operations first and is still young
