Cloudflare announced today they have open-sourced the code to Tokio-Quiche as their async QUIC library that combines their previously-open-sourced Quiche QUIC implementation with Rust's Tokio async runtime.

With Tokio-Quiche you end up with a Rust-based asynchronous wrapper around the Quiche QUIC code:

"Today we’re announcing the open sourcing of tokio-quiche, our battle-tested, asynchronous QUIC library combining both quiche and the Rust Tokio async runtime. Powering Cloudflare’s Proxy B in Apple iCloud Private Relay and our next-generation Oxy-based proxies, tokio-quiche handles millions of HTTP/3 requests per second with low latency and high throughput. tokio-quiche also powers Cloudflare Warp’s MASQUE client, replacing our WireGuard tunnels with QUIC-based tunnels, and the async version of h3i."

Tokio-Quiche is available as a Rust Crate .

The code is open-source now as part of their Quiche project on GitHub . More details on today's open-source milestone via the Cloudflare blog .
