Would you recommend Rust over Elm?

A few days ago I started to learn Elm with the goal to create a new front end for lemmy.

At the same time I want to create tui applications, which are really modern.

So someone recommended Crate tui, which is a Rust library.

Should I keep learning Elm or should I switch to Rust or should I even learn both, even if it takes a lot of time and energy?
