Quick guide - Create object graph

class ctor {
public:
  explicit ctor(int i) : i(i) {}
  int i;
};

struct aggregate {
  double d;
};

class example {
 public:
  example(aggregate a, const ctor& c) {
    assert(87.0 == a.d);
    assert(42 == c.i);
  };
};

int main() {
  const auto injector = di::make_injector(
    di::bind<int>.to(42),
    di::bind<double>.to(87.0)
  );

  injector.create<example>();
}
