How Cloudflare’s tokio-quiche Makes QUIC and HTTP/3 a First Class Citizen in Rust Backends

Cloudflare has open-sourced tokio-quiche, an asynchronous Rust library combining its production-tested quiche QUIC implementation with the Tokio runtime. This enables first-class QUIC and HTTP/3 support in Rust backends. The library powers Apple's iCloud Private Relay, next-gen Oxy-based proxies, and WARP's MASQUE client, handling millions of HTTP/3 requests per second in production environments.
