Capturing static member variable inside lambda function

I want to know if I can capture a static member variable of a class inside the lambda function(The lambda function is being used inside a static member function of the same class).

I've been trying the following but I'm not able to compile the code:

  #include<string>
  #include<iostream>

  using namespace std;

  class test_temp
  {
          public:
              static string name;
              static int count_of_letters();
  };

  string test_temp::name="Vishal";
  int test_temp::count_of_letters()
  {
        auto result = [&test_temp::name]() {return(test_temp::name.size());};

  }

  int main() {
  int res=test_temp::count_of_letters();
  cout<<endl<<res<<endl;
  }

Is there any way to capture the static member variable in this way?

Modified Code(after doing the suggested changes)

#include<string>
#include<iostream>

using namespace std;

class test_temp
{
        public:
            static string name;
            static int count_of_letters();
};

string test_temp::name="Vishal";
int test_temp::count_of_letters()
{
        auto result = []() {return(name.size());};
        result();
}

int main() {
int res=test_temp::count_of_letters();
cout<<res<<endl;
}
