usingforward_list=std::forward_list<T,std::pmr::polymorphic_allocator<T>>; } (2)(C++17 起) std::forward_list是支持从容器中的任何位置快速插入和移除元素的容器。不支持快速随机访问。它实现为单向链表,且实质上与其在 C 中的实现相比无任何开销。与std::list相比,此容器在不需要双向迭代时提供更好的...

std::list est implémenté comme une liste doublement chaînée. Par rapport à std::forward_list, ce conteneur offre la possibilité d'itérer dans les deux sens, au prix d'une occupation mémoire plus importante. std::list répond aux exigences de Container, AllocatorAwareContainer, ...
