Re Fuchsia: "They use a lot of Rust, and plan to use more." When I look at Fuchsia source I don't see much Rust. There is Fargo, a Cargo wrapper that integrates Rust into the Fuchsia build system, but I don't see a lot of actual Rust code in the system. What am I missing? I've cloned Topaz, Zircon and some other large Fuchsia repos, but I see only a smattering of Rust source.
