package main   import (   "log" )   type meta struct {   name string   age int } func (m *meta) copy(dest *meta) {   *dest = *m } func main() {   a := meta{name:"aaaaaaa", age:123}   log.Println(a)   var b meta   a.copy(&b)   b.name="fly"   b.age = 77   log.Println("b:", b)   log.Println("a:", a) }

　　其实，struct 对象直接赋值给其它变量，就可以了。赋值时，为值拷贝。
