Inherit privately from NonCopyable when a type must not be copied. The copy constructor and assignment operator are private, so a derived class cannot copy or assign, and neither can a caller. The result is a compile-time error, not a run-time failure.
Private inheritance is the usual form: NonCopyable is not part of the public interface. Public inheritance also prevents copies, but it exposes the mixin as a base. Do not try to make a type copyable again in a further derived class; the private members of NonCopyable stay private. Types that need to be moved but not copied still inherit here and define their own move operations.
