Just to make sure: did you actually change it according
to the changelog? It still looks like a runtime assertion
to me, but I don't really understand any rust.
Umm... I'm not sure what happened there.
Sorry, I'll resend it. I ran into some unrelated pain with bindgen
versions while trying to compile-test this, and along the way I must
have somehow dropped the actual v2 change...
