If this was built on top of #425 this would allow removing the const N: usize generic, and replace the pointer with NonNull<VecView<T>>. #425 does not offer the View functionality for String to keep the PR small, but it would be easy to add it.
It is worth considering because merging this PR and releasing before merging #425 would make it a breaking change to remove the const generic, so there would need to be 2 implementation of drain, one for the view and one for the owned type.

Yes, I agree it makes sense to base this on VecView instead.
