我可以将std :: basic_string用于非字符类型的东西吗？

#include<iostream>
#include<string>

template<typename T>
struct CustomChar {
    T value;
    CustomChar(T v) : value(v) {}
    operator T() const { return value; }
};

template<typename T>
std::ostream& operator<<(std::ostream& os, const CustomChar<T>& cc) {
    os<< static_cast<int>(cc.value);
    return os;
}

int main() {
    std::basic_string<CustomChar<int>> intString;
    intString.push_back(CustomChar<int>(1));
    intString.push_back(CustomChar<int>(2));
    intString.push_back(CustomChar<int>(3));

    std::cout << "Integer string: ";
    for (const auto& c : intString) {
        std::cout << c << " ";
    }
    std::cout<< std::endl;

    return 0;
}
