There's an effort to write a Ruby implementation in Rust: https://github.com/artichoke/artichoke https://github.com/artichoke/artichoke At the moment it wraps the mruby VM, but I think Ryan's plan is to switch to the CRuby YARV VM and then replace it with a VM written in Rust. I'm also working on a CRuby JIT compiler written in Rust using CraneLift (a new compiler written in Rust).
