More clear documentation for NonNull<T> Rephrase and hopefully clarify the discussion of covariance in `NonNull<T>` documentation. I'm very much not an expert so someone should definitely double check the correctness of what I'm saying. At the same time, the new language makes more sense to me, so hopefully it also is more logical to others whose knowledge of covariance basically begins and ends with the [Rustonomicon chapter](https://doc.rust-lang.org/nomicon/subtyping.html). Related to #48929. |
