title: "error: no match for 'operator='" Making 1 vector copy to another
body: <p>So i have made a instance of a class and now I am trying to use a getter to get the vector of structs that i have.</p>
  
  <pre><code>  struct posesData{
  double xInMeters;
  double yInMeters;
  double direction;
  }
  </code></pre>
  
  <p>So now I have created a instance of the class rangeAndPosesFiles which loads the files and parses it into data structures IE the vector.</p>
  
  <pre><code>private:
    char map[50][50];
    rangeAndPoseFiles files;
    vector&lt;posesData&gt; poses;
    int amountOfValidPoints;
    int discoveredItems[41][8];
  
  public:
   robotAndEnviroment(){
    amountOfValidPoints = 0;
    mapFill();
    poses = files.getPosesData();
    derp();
  }
  </code></pre>
  
  <p>So as you can see this line "poses = files.getPosesData();" This is where the error is being generated.</p>

  <p>I just want to get the vector from the rangeAndPoseFiles class and copy it to the RobotAndEviroment class But i get the error, how come?</p>
