While I have you, how close is the Rust incremental search support? It sounded like regex-automata might make it possible but hard to easily get a sense of high level progress from a GitHub issue.

I'm not working on it. The current status is that other people are working on trying to write it themselves on top of regex-automata in a way that works for their specific use case. That was my high level strategy: release a separately versioned library with the regex internals[1] exposed so that others can experiment and build on top of it.
The regex-automata crate exposes the low level DFA (and lazy DFA) transition function. So you can pretty much do some kind of stream searching out of the box today (certainly at least what Go provides): https://docs.rs/regex-automata/latest/regex_automata/#build-...
Bottom line here is that if you're looking to implement stream searching in Rust, then you should be able to go out and build something to do it today with regex-automata. But you aren't going to get a streamlined experience. (And whether you ever will or not remains unclear to me.)
The regexp.Regexp.FindReaderIndex and .FindReaderSubmatchIndex methods tell you the position of the match.
Thanks for the correction!
