You'll learn Rust faster with AI and should be able to solve it yourself.
You're unlikely to wind up in such a situation though. The design work Claude does in Rust is really sensible and idiomatic, and I really don't think you'll be unable to refactor or redesign things. Claude is extremely good with Rust generation, refactoring, and manipulation.
I'll go as far as to say that AI has removed most of the complaints people had with learning or using Rust. It's not even a speed bump now.
I would imagine this assumes the operator is still familiar with the borrow checker, lifetimes, etc. Otherwise how can the human operator know if what Claude does is actually sane (i.e. it compiles but doesn't do what it actually should)?
Come on now, how do you learn anything if you just tell claude to do something and feed it error messages?
Yeah, I don't think you really learn a language with agentic coding, at least you wont become fluent writing it. I currently use copy pasta chatbot help to write some C code and I am still often stuck how to progress manually. And I refactor a lot because the LLM code is subpar for me.
