Ah, missed this, sorry. My work essentially allows you to write `target[DirectoryInfo].path` in rules. I don't think there's much overlap here with this work. You could, of course, special case...

I'd love to, but I'm no longer working on bazel, so I don't get any time to allocate to rules_rust, since I've already had to allocate my 20% project to...

I think we might be getting confused because we're using different terminology. `pydantic`, in your example, is a repository created by the pip module extension. (`@pip//pydantic` is actually an alias...
