So can unique_ptr be used safely in stl collections?

Question

I am confused with unique_ptr and rvalue move philosophy.

Let\'s say we have two collections:

std::vector> autoCollect         


        

Answer 1

The unique_ptrs are being moved using their move constructor. unique_ptr is Movable, but not CopyConstructable.

There's a great article on rvalue references here. If you haven't read about them yet, or are confused, take a look!
