Looking at the original issue, I did some research (rust-lang/rust#14015) on this a while back and I think I concluded that this was hard/impossible to do in the general case.
I would be very happy to hear about a more specific proposal in a new issue.

(In my case I'm streaming stdout of a child process on a server back to a browser.)
Would it be possible to give a closure that acted on the match and returned the replacement rather than trying to return matches in the stream? That way you might be able to still deal with &str rather than having to allocate.
I do wonder if we're really asking for a pure rust SED clone.

@gilescope This issue is extremely old. Please see #425 for updated and very in depth discussion on this task. Closures or not-closures isn't really the issue.

Thanks for pointing me in the right direction, yes I can see it's non-trivial.
