Is there some way i can make sure only one instance of a struct is ever created?

Yes, it's possible.

struct TheStruct{  static TheStruct & Instance()  {    static TheStruct instance;    return instance;  }private:   TheStruct();  TheStruct(const TheStruct &);};

There's a very high probability that doing this is useless (i.e. you don't need the protection), and a high probability that your design will cause you great pain in a few weeks or months.

A singleton or similarly a monostate.

*A monostate allows multiple instances but all instances share the same state.

[edit]

You could probably avoid both however.
