And no one of the sublinks team can do rust really, so it was just a matter of what languages can be learned faster and/or have already good knowledge about a programming language.
Nutomic, one of the main Lemmy devs, didn’t know Rust either when he started contributing. It’s really not so difficult to learn as it seems.
I’d love to help anyone learn btw. I unfortunately don’t have the time to contribute to Lemmy myself but I love teaching so if anyone would like to learn some Rust, hit me up.
