It depends on what you want to do, of course, but for back end servers the Rust ecosystem is relatively immature. There is nothing comparable to ZIO in Rust world, for example.
What's more important than the current state is the direction where it's heading.

Scala has unfortunately fizzled out, I would say mainly because of incompetent leadership (or more precisely academia-driven) but also because the alternatives got much better since it got introduced (Java mainly). Which is a shame as it is a great language that offers elegance and great power.
