如何定义自定义类型的通用std :: list？

#include<iostream>
#include <list>

class CustomType {
public:
    CustomType(int value) : m_value(value) {}
    int getValue() const { return m_value; }
private:
    int m_value;
};

std::list<CustomType> customList;

customList.push_back(CustomType(42));
customList.push_front(CustomType(100));

for (const auto& element : customList) {
    std::cout << "Value: "<< element.getValue()<< std::endl;
}
