Steel seems alright: https://github.com/mattwparas/steel

There are other Lisps too (https://github.com/alilleybrinker/langs-in-rust) though I think they’re less actively maintained.

Steel has worked well for me as far as I’ve used it. It’s easy to get going and the partnership with Helix will surely give it a popularity boost over the next year or so.
