Detailed Description

A callable that creates service instances without container access.

Simple factories don't need container access for dependency resolution. They're useful for services without dependencies or with external dependencies.

Example usage:

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