Expose group_info() for Regex::Captures

[wesleyel]

Hi there!

I'm writing a wrapper for regex crate's Regex::Captures struct, and for this I need to get the group_info member of regex_automata::util::captures::Captures.

But I found that the Regex::Captures type currently does not have a way to export its caps attribute or the group_info() method of the caps attribute.

Would regex willing to accept a patch that expose group_info()? Or Maybe I should head to use regex_automata?

Thanks!

You can't just expose GroupInfo. That would make regex-automata a public dependency of regex, which it is very intentionally and very carefully not. So to do that, we'd need to make a wrapper type for it.

In general, I do not expand the API of regex without good reason, and I don't see any motivating examples here to argue in favor of that direction.

Yes, you should be using regex-automata.
