std::unique_ PTR < T> and boost:: scoped_ Particularity of PTR ＜ t ＞

std::unique_ptr<T> And boost::scoped_ptr<T> The underlying implementation principle type of , I don't know who it is " reference " The implementation of another , But it doesn't matter .

std::unique_ptr<T> And boost::scoped_ptr<T> all Copy constructs and assignment functions are disabled , So we can't do it STL Elements in the container , As STL Elements in the container , So for push_back() To call the assignment function , But they all disable copy constructs and assignment functions , So we can't do it STL Elements in the container .

But there is another way , Use std::move().std::move() Is to convert an l-value to an R-value .
