C++核心准则C.101:赋予容器值语义‍

C.101: Give a container value semantics

C.101:赋予容器值语义‍

Reason(原因)‍

Regular objects are simpler to think and reason about than irregular ones. Familiarity.

常规对象相比非常规对象更容易理解和思考。这是亲和度方面的意义。

Note(注意)

If meaningful, make a container Regular (the concept). In particular, ensure that an object compares equal to its copy.

如果可以理解，让容器符合常规(概念)。尤其要保证对象和它的拷贝比较时结果相等。

Example(示例)‍

void f(const Sorted_vector& v)
{
    Sorted_vector v2 {v};
    if (v != v2)
        cout << "insanity rules!\n";
    // ...
}

Enforcement(实施建议)
