Replaces the managed object with the one managed by r. The object is shared with r. If r manages no object, *this manages no object too.
std::weak_ptr<T>(r).swap(*this).std::weak_ptr<T>(std::move(r)).swap(*this).| r | - | smart pointer to share an object with |
*this.
The implementation may meet the requirements without creating a temporary weak_ptr object.
