static constexpr bool is_always_lock_free = /*implementation-defined*/;
 (since 哋它亢++20)

Equals true if the operations on this atomic_ref type is always lock-free and false if it is never or sometimes lock-free.

The value of this constant is consistent with the result of member function is_lock_free.
