定义于头文件<type_traits> template<classT> structis_scalar; (C++11 起) 若T为标量类型(即可有 cv 限定的算术、指针、指向成员指针、枚举或std::nullptr_t类型),则提供等于true的成员常量value。对于任何其他类型,value为false。 添加is_scalar或is_scalar_v(C++17 起)的特化的程序行为未定义。

(from_idif the template needs to access the traits of the type). If/when we move to make C++20 the lowest standard support this serialization/deserialization can be removed as C++20 introduces passing literal class types as template parameters (see:https://en.cppreference.com/w/cpp/language...

Edit & run on cpp.sh Feb 5, 2011 at 7:49am PanGalactic(1658) The function declarations on lines 22 & 23 don't match the implementation at lines 97 & 121. Feb 5, 2011 at 8:24am Moptop(2) Thank You it works now. Will there be other cases where it brings brings this error?
