Go学习:Stringer

Stringer是go语言中一个常用的系统接口,Stringer有一个String函数,相当于java当中的toString

package stringsimport "fmt"type UserCommon struct {Name string
}func (u UserCommon) String() string {return fmt.Sprintf("UserCommon: {Name=%s}", u.Name)
}func (u UserCommon) Get() string {return u.Name
}

package mainimport ("fmt""learngo/use/strings"
)func main() {u := strings.UserCommon{"番茄炒蛋"}// 番茄炒蛋fmt.Println(u.Get())// UserCommon: {Name=番茄炒蛋}fmt.Println(u.String())
}
