c++ - How to declare a vector of structure of a class -

i have class structure in it. how create vector of structure type?

here example:

class { public:     struct mystruct {            mystruct (int _label, double _dist) : label(_label), dist(_dist) {}            int label;         double dist;     }; } 

now in class "a" there function below.

   myfunc ( vector<mystruct> &mystry ); 

so question need call function vector of structure. how can declare this?

use scope operator :::

std::vector<a::mystruct>
