Compiler-generated move member functions on static data members

Question

In Effective Modern C++, item 17 ( Understand special member function generation ), Scott Meyers said that the generated special move member functions (move constructor and move assignment operator) perform “memberwise moves” on the non-static data members of the class .

The move operations are generated only if they're needed, and if they are generated, they perform “memberwise moves” on the non-static data members of the class.

I tried to understand the non-static condition but I couldn't, can anyone explain to me why can't they perform that on static data members?

Answer 1

I think it simply referres to static members, as here:

struct A{
   static int s; // static member, (not moved or copied when moving/copying an instance
   int w; // non-static member
};

Answer 2

Because static members are not part of the created objects from that class. Though they don't need to be moved (or copied in case of copy constructor).
