如何在c++ shared_ptr中使用lambda作为删除器来创建对象缓存？

#include <iostream>
#include <memory>

class Object {
public:
    Object(int id) : id_(id) {
        std::cout << "Object " << id_ << " created." << std::endl;
    }
    ~Object() {
        std::cout << "Object " << id_ << " destroyed." << std::endl;
    }
    void DoSomething() {
        std::cout << "Object " << id_ << " is doing something." << std::endl;
    }
private:
    int id_;
};

int main() {
    // 使用lambda作为删除器
    auto deleter = [](Object* obj) {
        std::cout << "Custom deleter called for Object " << obj->GetId() << "." << std::endl;
        delete obj;
    };

    // 使用shared_ptr创建对象缓存
    std::shared_ptr<Object> cache(new Object(1), deleter);

    cache->DoSomething();  // 对象缓存可以像普通指针一样使用

    std::cout << "End of main function." << std::endl;
    return 0;
}
