tokio-uring

This crate provides io-uring for Tokio by exposing a new Runtime that is compatible with Tokio but also can drive io-uring-backed resources. Any library that works with Tokio also works with tokio-uring. The crate provides new resource types that work with io-uring.

Getting started

Using tokio-uring requires starting a [tokio-uring] runtime. This runtime internally manages the main Tokio runtime and a io-uring driver.

In your Cargo.toml:

[dependencies]
tokio-uring = { version = "0.5.0" }

In your main.rs:

use tokio_uring::fs::File;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    tokio_uring::start(async {
        // Open a file
        let file = File::open("hello.txt").await?;

        let buf = vec![0; 4096];
        // Read some data, the buffer is passed by ownership and
        // submitted to the kernel. When the operation completes,
        // we get the buffer back.
        let (res, buf) = file.read_at(buf, 0).await;
        let n = res?;

        // Display the contents
        println!("{:?}", &buf[..n]);

        Ok(())
    })
}

Requirements

tokio-uring requires a very recent linux kernel. (Not even all kernels with io_uring support will work) In particular 5.4.0 does not work (This is standard on Ubuntu 20.4). However 5.11.0 (the ubuntu hwe image) does work.

Project status

The tokio-uring project is still very young. Currently, we are focusing on supporting filesystem and network operations. Eventually, we will add safe APIs for all io-uring compatible operations.
