Sorry for the dup. Could have sworn that didn't show up in a search, but I see it now!

It's been an annoying issue, getting a rustup installation that works for the piwheels process. There's a PR for it at https://github.com/piwheels/piwheels/pull/328 but it's a slow/difficult testing process. Need to take another look soon.

@bennuttall cryptography is starting to become a pain - it's now got 3 open security vulnerabilities we can't get fixed as the pi installation is not working with newer versions.

Unfortunately, it's unclear (to me) what's missing in the PR linked - or how one could assist in getting that merged, to get cryptography working again.

We've run builds with the changes in that PR and the builds still fail
