Cloudflare re-writes core system in Rust

Beeftopia writes: Cloudflare's core system, named FL, which Cloudflare describes as "the brain of Cloudflare", has been re-written in Rust. They report, "We weren’t starting from scratch. We’ve previously blogged about how we replaced another one of our legacy systems with Pingora, which is built in the Rust programming language, using the Tokio runtime. We’ve also blogged about Oxy, our internal framework for building proxies in Rust. We write a lot of Rust, and we’ve gotten pretty good at it...We built FL2 [FL replacement] in Rust, on Oxy, and built a strict module framework to structure all the logic in FL2." They go on to say, "Rust... eliminates entire classes of bugs that plagued our Nginx/LuaJIT-based FL1, like memory safety issues and data races, while delivering C-level performance."
