c++ - Binary Tree with std::unique_ptr -

I'm actually using std :: unique_ptr to make binary trees.

Actually, I use an algorithmic tour, which calculates the distance from the distance matrix, at least! In my algorithm, I encountered myself with the problem of std :: move () with std :: unique_ptr .

My tree has been created, but do not just "make the branch" on the root node and

Here is the code where I have a problem:

  Node = std :: move (node.get () -> addChild ());   
 The function  addChild   refers to the new child (= std :: unique_ptr & lt; node & gt;) .  
 I really need to change the "node" to complete my algorithm, so how can I fix it?   
 
 
  addChild to return  unique_ptr  Instead of returning a reference, the result will be a rvalue without the need of an artist with the result  std :: move . In your current code, you pass an original reference for  std :: move , which resulted in it still being a real reference and the copy constructor instead of  std :: unique_ptr's constructor Attempt to invoke .
