It does alright with Rust, but you can't assume it works as intended if it compiles successfully. The issue with current AI when solving complex or large scale coding problems is usually not syntax, it's logical issues and poor abstraction. Rust is great, but the borrow checker doesn't protect you from that.

I'm able to use AI for Rust code a lot more now than 6 months ago, but it's still common to have it spit out something decent looking, but not quite there. Sometimes re-prompting fixes all the issues, but it's pretty frustrating when it doesn't.
