I actually started the project in Isabelle: https://github.com/Kha/electrolysis/tree/isabelle/thys. Automation was nice, translating Rust traits not so much. You really want them to be type classes, which Isabelle only supports for the single-parametric case.

As of right now, the project would probably be easier in Coq. But I'm confident that Lean 3 will eventually feature more powerful automation (and no Ltac). It is, after all, being developed by Leonardo de Moura, one of the creators of Z3.

All of these look really interesting, I'll take a look at time. Thanks everyone!
