Going through a blog about dependency injection. For the interface in their example, they use a struct with pure virtual methods instead of a class, and then inherit from the interface as a class.
struct IEngine
{
virtual void Start() = 0;
virtual void Stop() = 0;
virtual ~IEngine() = default;
};
class V8Engine : public IEngine
{
void Start() override { /* start the engine */ }
void Stop() override { /* stop the engine */ }
};
My instinct would have been to make the IEngine interface a class instead. Is there a difference between using a struct vs class for the interface here? Would there be a situation where you would prefer to use one over the other?
