That's exactly the point I wanted to make (but failed to) a couple months ago [1] - that for the (few) tasks you'd use C for (such as writing language runtimes) Rust might not be a good fit. If it isn't a good fit for regexp, it might not be a good fit for JavaScript either.

It’s not that rust wasn’t a good fit. It’s that writing a regex engine from scratch in rust to be integrated into their c++ code base wasn’t the right choice for them when compared against integrating an existing c++ solution.
