在 header 文件中声明构造函数 '= default' 是否会破坏 ODR

Question

If I define the destructor (or any autogenerated constructor) as default like this:

struct A { 
   ~A() = default;
};

And then include this in several translation units, does this break the ODR? Can someone walk me through the steps at on the ODR page? Because i am struggling to understand if the compiler generated destructor will be inline or some other effect to prevent it from breaking the ODR.

Answer 1

No ODR violation. Member functions are implicitly inline if they are defined inside the class body.
