Example
Struct methods are very similar to functions:
type User struct {
name string
}
func (u User) Name() string {
return u.name
}
func (u *User) SetName(newName string) {
u.name = newName
}
The only difference is the addition of the method receiver. It may be declared either as an instance of the type or a pointer to an instance of the type. Since SetName() mutates the instance, the receiver must be a pointer in order to effect a permanent change in the instance.
For example:
package main
import "fmt"
type User struct {
name string
}
func (u User) Name() string {
return u.name
}
func (u *User) SetName(newName string) {
u.name = newName
}
func main() {
var me User
me.SetName("Slim Shady")
fmt.Println("My name is", me.Name())
}
