Golang中复制结构体，可以使用赋值语句
package main
import (
"fmt"
)
type Dog struct {
age int
name string
}
func main() {
roger := Dog{5, "Roger"}
mydog := roger
fmt.Printf("roger addr %p\n", &roger)
fmt.Printf("mydog addr %p\n", &mydog)
fmt.Println("Roger and mydog are equal structs?", roger == mydog)
mydog.name = "piggie"
fmt.Println("Roger and mydog are equal structs?", roger == mydog)
}
执行结果
roger addr 0xc000092000 mydog addr 0xc000092020 Roger and mydog are equal structs? true Roger and mydog are equal structs? false
可以看出，roger跟mydog在内存中的地址不同。并且对mydog修改属性，对roger没有影响。
但是注意，这里的Dog结构体中的属性，都是值类型。如果是 引用类型 的话，复制的是 指针 ，而不是具体的值。所以通过赋值语句对结构体的拷贝，是 浅拷贝 。如需对引用类型属性进行深拷贝，可以通过手动创建的方式，或者使用实现了deepcopy功能的第三方包
