Prevent scoped enum to be copyable / moveable?

原文 2017-06-09 10:00:04 8 1 c++/ c++17

Perhaps silly question:

Is there a way in C++ to prevent an enum class type to be copyable?

No. Enumerations are integers. And integers are always copy/moveable.

You could of course make an actual class that is constructed from the enumerations. And that class can be immobile. But that's about it.

trivially moveable but not trivially copyable

Moveable but Non-Copyable Exceptions

std::tuple with non moveable/copyable type

Make a class with an reference member copyable and moveable

gmock SetArgReferee: Set a non-copyable non-moveable object

Adding struct containing not copyable/moveable object to std::map

Class-scoped enum

Switching on scoped enum

Modifying scoped enum by reference

Convert scoped enum to int
