I worked on a Ruby codebase that moved to Rust - I think that part is mostly cargo-culting cool things in the news to be perfectly honest. There’s type safety advantages, but if Ruby’s performance envelope was even conceivably acceptable for your use-case there are likely better options. I strongly suspect a lot of the friction between Rust and only-C/C++ developers is the product of a bunch of people coming at Rust from higher level languages parroting lines about safety, and then looking at you blankly if you ask how it handles nested pointer indirection.

But I don’t think that applies to the people actually driving the language forward, just those talking a big game on HN/Reddit.
