CppCon 2015: Andrei Alexandrescu “std::allocator...”

推荐理由

It really opened my eyes to how one could very elegantly make a very complex and high-performance heap allocator

说明

这是2015年由CppCon发布的一部演讲，主题归在C, C++, Rust, Go & systems languages。它讲的是memory allocators这一支里的具体问题，而不是把整个领域扫一遍。适合想看推导、证明或实现细节的人。内容上可以概括成：Andrei Alexandrescu's CppCon 2015 talk argues that std::allocator is badly designed. He proposes building high-performance allocators from small composable, templated pieces.这些读者给出的理由，核心是：HN repeatedly recommends it as an entertaining, mind-opening talk on allocator design and composable generic programming.讲法不绑某一条新闻，过几年仍然可以当材料看。从2017年到2025年，有7位不同的读者在11个不同月份把它推荐出来，其中明确叫别人去看的有7次。适合一次性看完。讲者把一个判断讲透，演示是在给这个判断配例子。如果已经会了基本定义，就把注意力放在它怎么把memory allocators变成能跟着复述的例子。
