std::swap(std::set) 特化std::swap 算法 (函数模板) erase_if(std::set) (C++20) 擦除所有满足特定判别标准的元素 (函数模板) 推导指引 (C++17 起) 注解 成员类型 iterator 与const_iterator 可能是同一类型的别名。这表明以这两个类型为形参类型的一对函数重载可能违背单一定义规则。因为
An input iteratorisupports the expression*i, resulting in a value of someobject typeT, called thevalue typeof the iterator. An output iteratorihas a non-empty set of types that arewritable(until C++20)indirectly_writable(since C++20)to the iterator; for each such typeT, the expression*i=...
