How to pass a std::vector<struct> into kernel function?

In my kernel function,I want to use the value in the vector and change the value. Here is my struct.

struct A 
{
  float a;
  float b;
};
struct B
{
  float c;
  float d;
};
struct my
{
  float q;
  std::vector<B> ps;
  A dimension;
};

How to pass the std::vector<my> mystruct into kernel function and change the ps value,dimension value and q value? I'm a newer in CUDA.
