Golang Cast Interface To Struct

1. The interface object can be converted to struct through the below code:

Type person1 struct {
 Username string
 Lastname string
 }
 Func printIfperson1(object interface{}) {
 person1, ok:= object. (Person1)
 If ok {
  fmt.printf(“Hello %s ! \n” person1.username)
 }
 }
