I am having a different experience than a lot of other commenters here vibe coding with Rust. I am not a Rust programmer or evangelist. I have implemented a drop-in Bash replacement/clone in Rust that passes the upstream Bash test suite and a whole battery of its own. It is a tiny bit faster than Bash itself but consumes a bit more memory. But Codex and Claude both did a great job with it.

I also had it implement a wasm geodesic calculator in Rust and it's amazing and in my use case is better than geodesiclib using the same updated algorithm.

I'm a "C-nile" Rust folks love to hate and did my first hacking in C Deep Blue C on Atari 8-bits. But I'm very impressed with these products and with the ability to leverage some features of Rust with them. (e.g. audit every unsafe instance and define its invariants, etc.)

I also agree with the commenter who said these LLMs are today, at the present moment, good at Go. The only language I notice it seems to be really good above and beyond others at is javascript, I assume because there's so much of it.
