Thanks for the PR!
But miri cannot run through FFI AFAIK. Do you have any result or action report test on your side?

Most of the unit tests don't do any FFI, so I figured it was useful to have the coverage with miri where it is possible.

Miri didn't flag anything. I just think it is a useful sanity check to have.
