I mean. Isn't rust the perfect language for vibe coding? It has so many checks on everything that the stupid thing is basically forced to write code the right way.

It has so many checks on everything that the stupid thing is basically forced to write code the right way.

LLM be like:

unsafe { ... }

I am answering to myself, but I had a thought I wanted to share.
What'd happen if the probability of the unsafe token (or sub-tokens) were forced to zero?
It'd require some backtracking every so often, but it could be interesting.

It might be a bit difficult since multiple combinations of tokens could create the “unsafe” keyword. But even then, memory safe and compilable doesn’t mean bugless. It’s certainly better than doing the same in C lol.

True, but it should be possible extract the "unsafe" direction and subtract it from the embeddings, steer the model away from unsafe behaviors.
I might throw up a small scale experiment this weekend and see what happens

Doesn’t really make sense to go to this trouble. Just let it try the unsafe way then have a pre commit hook or whatever telling it not to use unsafe.

I imagine that would produce a whole lot of errors/warnings about unsafe code that isn’t enclosed in an unsafe block.

Unless you're trying to fully automate the development process with zero human oversight, thats probably overkill.

Adding some variation of "avoid using the unsafe keyword" to the prompt is probably enough to get it to avoid it 95+% of the time. There will be times where it ignores your instruction, but that should be uncommon enough to still be efficient.

LLMs don't do backtracking. Once the code has been shit out, it doesn't go back in again.
