Could also be nice as it means the Rust parts are smaller and so its slow compiler speed isn't as much of a bother. You get the safety and runtime speed of Rust with the fast iteration cycle of Elixir. Best of both worlds type of thing.

I often find FFI more annoying than it should be (ie something always breaks somewhere), I try to avoid it where possible.
