UraniumDI is a dependency injection library for modern C++.

1. Write your interfaces and implementations:

   // All service interfaces must derive from IObject
   class ILogger : public UN::IObject
   {
   public:
       // And declare RTTI with a macro, UUID here is used to identify the type
       UN_RTTI_Class(ILogger, "A521C28C-A4CD-491F-B89E-B666B57429BF");
   
       virtual void Log(const std::string_view& message) = 0;
   };
   
   // Implementations must derive from Object<IInterface>
   class MyLogger : public UN::Object<ILogger>
   {
   public:
       UN_RTTI_Class(MyLogger, "71963929-6C8A-42F5-B6E9-70F23510C71A");
   
       inline MyLogger() {}
   
       inline void Log(const std::string_view& message) override
       {
           std::cout << message << std::endl;
       }
   };

2. Register your services within an IoC container:

   UN::DI::ContainerBuilder builder{};
   builder.Bind<ILogger>().To<MyLogger>();
   builder.Bind<IDatabase>().To<MyDatabase>().InSingletonScope();
   
   Ptr container = builder.Build();

3. And resolve them:

   UN::Ptr logger = container->Resolve<ILogger>().Unwrap();
   logger->Log("Message from logger!");
   
   UN::Ptr db = container->Resolve<IDatabase>().Unwrap();
   logger->Log(std::format("Data loaded: {}", db->LoadData()));
