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
