I think you would really appreciate Rust for backend web dev. Quite a few people who were once upon a time hardcore rubyists gravitated to Rust and became some of its greatest contributors: Steve K., Sean G., Carl L., Florian G., and many more.
I like Rust a lot - especially since I have a C++ background - unfortunately I don't see any opportunities to move to it ATM, but I haven't really tried hard enough - maybe I'll take a month off after my current project to write something substantial in it and try to find a Rust gig.
