Summary
This post announces the open-sourcing of 'tokio-quiche,' a battle-tested asynchronous QUIC library that combines the 'quiche' QUIC implementation with the Rust Tokio async runtime. It powers critical services like Apple iCloud Private Relay and Cloudflare Warp, handling millions of HTTP/3 requests per second. The library aims to lower the barrier to entry for integrating QUIC and HTTP/3, promoting industry adoption of these new standards and privacy-preserving technologies. It utilizes an actor model for efficient asynchronous operations and provides abstractions for application protocols over QUIC, such as HTTP/3.
