推荐uep · 原文2018年2月

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c++ exception handling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 on handling exceptional control flow declaratively in C++. It uses scope guards with success and failure variants, built on std::uncaught_exceptions, to replace ad hoc RAII classes and rethrowing try/catch blocks.这些读者给出的理由，核心是：Pointed to in threads on defer, scope_exit and RAII as the clearest treatment of scope guards.讲法不绑某一条新闻，过几年仍然可以当材料看。从2016年到2022年，有2位不同的读者在2个不同月份把它推荐出来，其中明确叫别人去看的有0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c++ exception handling变成能跟着复述的例子。
