Can you elaborate re: issues and lots of work required? I think it's generally to be expected that non-C language support in the kernel would be hard...
It's very Chrome and C++ specific, but the problems will likely be similar in practice.
Ah, right, I'd read that - but it's for C++, so it's a bit different than the kernel situation, and I actually had a much more positive reaction to it ("wow, seems like C++<->Rust is actually pretty far along"). Guess both are reasonable takeaways.
