有没有办法在成员变量上执行std::upper_bound？

#include <iostream>
#include <algorithm>
#include <vector>

class MyClass {
public:
    int value;
};

int main() {
    std::vector<MyClass> myVector;

    // 添加一些MyClass对象到myVector
    myVector.push_back({1});
    myVector.push_back({2});
    myVector.push_back({3});
    myVector.push_back({4});
    myVector.push_back({5});

    // 按照value的升序排序
    std::sort(myVector.begin(), myVector.end(), [](const MyClass& a, const MyClass& b) {
        return a.value < b.value;
    });

    MyClass target{3};

    // 使用std::upper_bound在myVector中查找大于target的元素
    auto upper = std::upper_bound(myVector.begin(), myVector.end(), target, [](const MyClass& a, const MyClass& b) {
        return a.value < b.value;
    });

    if (upper != myVector.end()) {
        std::cout << "Found element greater than target: " << upper->value << std::endl;
    } else {
        std::cout << "No element found greater than target" << std::endl;
    }

    return 0;
}
