Rust complexity is a bit overblown. I also revert automatically to it now if I feel like Typescript (Node.js) won't cut it, even for < 1K LOCs.
I may be biased since I've been using it for almost 6 years, but you mostly don't need to worry about lifetime annotations which IMO is the really foreign part if you are already comfortable with functional languages, especially since the compiler is unbelievably useful.
Many well-known Rust crates also account for the majority of the best all-around libraries I've ever personally used in any language, and you can actually use them without a PHD in build systems thanks to Cargo.
Re-usability is superb thanks to traits (composition over inheritance) and generics, even if still immature domains tend to be overly generic for the end-user (HTTP networking for instance, though it's getting better fast).
