无法在 C++ 向量和对象之间创建映射

问：

我正在尝试在粒子和它所在的位置之间创建映射。从本质上讲，我想要我的地图，其中 a 和 is a Particle。M[loc] = plocstd::vector <int>p

这是我拥有的代码：

#include <iostream> 
#include <vector> 
#include <string>
#include <algorithm> 
#include <map>
class Particle{
public: 
    std::vector <int> coords;                                        // the coordinates of the particles
    std::string ptype; 
    int orientation; 
    bool operator<(const Particle& rhs)const{
        return coords < rhs.coords; 
    }


    // constructor 
    Particle (std::vector <int> crds, std::string type_, int orientation_): coords (crds), ptype (type_), orientation (orientation_){

    }

    // destructor 
    ~Particle(){

    }

    Particle( const Particle &other); // copy constructor 

    // print location of the particle 
    void printCoords(); 

};


int main(int argc, char* argv[]){


  std::map <std::vector <int>, Particle> OccupancyMap;

  Particle p ({0,0,0}, "monomer", 0); 
  std::cout << p.ptype;
  Particle pdash = p; 
  OccupancyMap[p.coords] = pdash ;

}

当我尝试编译此代码时，我收到一条大量错误消息：

我不太明白这是怎么回事。这里错误的本质是什么？它指向什么概念？ 我将不胜感激你对我的任何建议。如果这是一个明显的问题，我深表歉意。
