      shared_lock& operator=( shared_lock&& other)noexcept;
      (since C++14)

      Move assignment operator. Equivalent toshared_lock{std::move(other)}.swap(*this);return*this;.

      Ifother is the same object as*this, there is no effect.

      Otherwise, if prior to this call*this has an associated mutex ((mutex() returns a non-null pointer) and has acquired ownership of it (owns() returnstrue), the mutex is unlocked by callingunlock_shared(). After this call,other has no associated mutex.
