If there are any members of the class, the move constructor will not be generated automatically?

Question

C++ / C#

1) Custom explicit constructor
2) Custom move constructor
3) Custom copy constructor
4) Custom assignment operator
5) Custom move assignment operator
6) Custom destructor
7) Primitive type private field

Answer 1

Implicitly-declared move constructor
If no user-defined move constructors are provided for a class type (struct, class, or union), and all of the following is true:

• there are no user-declared copy constructors;
  
• there are no user-declared copy assignment operators;
  
• there are no user-declared move assignment operators;
  
• there is no user-declared destructor.
  

then the compiler will declare a move constructor as a non-explicit inline public member of its class with the signature T::T(T&&).

Well, the custom move constructor excludes the automatic one.
So 2, 3, 4, 5, 6.
