I don't think this is the type you want. I am afraid your question was already somewhat ill-posed, which is why the answers also became confusing. The thing is, UnsafeCell is only relevant for shared references. If you do FFI and everything is behind a ptr indirection, then you do not have to worry about UnsafeCell. Just use *mut and wrap it in a newtype. The nomicon has some further information.
