Concept definition

template<typename F, typename T>
concept kcenon::common::concepts::ServiceFactory =  std::invocable<F, di::IServiceContainer&> &&
    std::convertible_to<std::invoke_result_t<F, di::IServiceContainer&>,
                        std::shared_ptr<T>>

Detailed Description

A callable that creates service instances.

A callable that creates a service instance.

Service factories receive a reference to the container (for resolving dependencies) and return a shared_ptr to the service instance.

Example usage:

template<ServiceInterface T, ServiceFactory<T> F>
void register_factory(IServiceContainer& container, F&& factory) {
    container.register_factory<T>(std::forward<F>(factory));
}
