How do I put a vector inside of a struct in Go?

问题

我正在尝试在Google的Go编程语言中将一个向量变量放入一个结构体中。目前我有以下代码：

期望的代码：

  1. type Point struct { x, y int }
  2. type myStruct struct {
  3.  myVectorInsideStruct vector;
  4. }
  6. func main(){
  7.  myMyStruct := myStruct{vector.New(0)};
  8.  myPoint := Point{2,3};
  9.  myMyStruct.myVectorInsideStruct.Push(myPoint);
  10. }

现有的代码：

  1. type Point struct { x, y int }
  3. func main(){
  4. myVector := vector.New(0);
  5. myPoint := Point{2,3};
  6. myVector.Push(myPoint);
  7. }

我可以在我的main函数中正常使用向量，但我希望将其封装在一个结构体中以便更容易使用。

I'm trying to put a vector variable inside a struct in Google's Go programming language. This is what I have so far:

Want:

  1. type Point struct { x, y int }
  2. type myStruct struct {
  3.  myVectorInsideStruct vector;
  4. }
  6. func main(){
  7.  myMyStruct := myStruct{vector.New(0)};
  8.  myPoint := Point{2,3};
  9.  myMyStruct.myVectorInsideStruct.Push(myPoint);
  10. }

Have:

  1. type Point struct { x, y int }
  3. func main(){
  4. myVector := vector.New(0);
  5. myPoint := Point{2,3};
  6. myVector.Push(myPoint);
  7. }

I can get the vector to work in my main function just fine, but I want to encapsulate it inside a struct for easier use.

我不确定这是否是您想要的，如果不起作用，请留下评论：

  1. package main
  3. import "container/vector";
  5. type Point struct { x, y int };
  7. type mystruct struct {
  8.     myVectorInsideStruct * vector.Vector;
  9. }
  11. func main() {
  12.     var myMyStruct mystruct;
  13.     myMyStruct.myVectorInsideStruct = new(vector.Vector);
  14.     myPoint := Point{2,3};
  15.     myMyStruct.myVectorInsideStruct.Push(myPoint);
  16. }
英文:

I'm not sure whether this is what you want, so leave a comment if it doesn't work:

  1. package main
  3. import "container/vector";
  5. type Point struct { x, y int };
  7. type mystruct struct {
  8. 	myVectorInsideStruct * vector.Vector;
  9. }
  11. func main() {
  12. 	var myMyStruct mystruct;
  13. 	myMyStruct.myVectorInsideStruct = new(vector.Vector);
  14. 	myPoint := Point{2,3};
  15. 	myMyStruct.myVectorInsideStruct.Push(myPoint);
  16. }

不确定这是否是您想要的，但是：

  1. package main
  3. import (
  4.     "fmt";
  5.     "container/vector";
  6. )
  8. type myStruct (
  9.     struct {
  10.         myVectorInsideStruct vector.IntVector;
  11.     }
  12. )
  15. func main() {
  16.     v := new(myStruct);
  17.     v.myVectorInsideStruct.Init(0);
  19.     for i := 1 ; i < 10 ; i++ {
  20.         v.myVectorInsideStruct.Push(i);
  21.     }
  23.     fmt.Printf("v.myVectorInsideStruct: %v\n", v.myVectorInsideStruct.Data());
  24. }
英文:

Not sure this is what you want, but:

  1. package main
  3. import (
  4.     &quot;fmt&quot;;
  5.     &quot;container/vector&quot;;
  6. )
  8. type myStruct (
  9.     struct {
  10.         myVectorInsideStruct vector.IntVector;
  11.     }
  12. )
  15. func main() {
  16.     v := new(myStruct);
  17.     v.myVectorInsideStruct.Init(0);
  19.     for i := 1 ; i &lt; 10 ; i++ {
  20.         v.myVectorInsideStruct.Push(i);
  21.     }
  23.     fmt.Printf(&quot;v.myVectorInsideStruct: %v\n&quot;, v.myVectorInsideStruct.Data());
  24. }
