当字符串长度较小时,我们用std::array的不malloc()的喜感;当字符串长度较长时,我们用std::string的动态内存便利性。 2)string_view。这个是从boost::string_ref移植过来的好东西。 3)屏蔽了底层的技术细节。发明这个东西,不再需要什么placement new之类的胡言论语。 char buf_[64]; new (buf_) std::string(...
The std::string_view offers the benefits of std::string's interface without the cost of constructing an std::string object.
