I can see this being useful in combination with Piston[1] to achieve scripting for game engines, in the same way Lua is normally used. Rust as a core for a game engine seems like a really great idea, considering the speed and safety benefits it provides.

Javascript seems like a great contender in this space to me. Btw, as well as using nodejs / v8, there are also Rust bindings for SpiderMonkey (Mozilla's JS engine): https://github.com/servo/rust-mozjs

(not super user-friendly yet, as this mainly exists for Servo - but there's enough here to embed Javascript scripts in your Rust projects!)
