处理引用父级的Struct字段的惯用方法

type Parent struct {
    Field1 string
    Field2 int
}

type Child struct {
    Parent *Parent
    Field3 string
}

func main() {
    parent := &Parent{
        Field1: "Value1",
        Field2: 123,
    }

    child := &Child{
        Parent: parent,
        Field3: "Value3",
    }

    // 访问父级字段
    fmt.Println(child.Parent.Field1) // 输出: Value1

    // 修改父级字段
    child.Parent.Field2 = 456
    fmt.Println(child.Parent.Field2) // 输出: 456
}

type Parent struct {
    Field1 string
    Field2 int
}

type Child struct {
    Parent Parent
    Field3 string
}

func main() {
    parent := Parent{
        Field1: "Value1",
        Field2: 123,
    }

    child := Child{
        Parent: parent,
        Field3: "Value3",
    }

    // 访问父级字段
    fmt.Println(child.Parent.Field1) // 输出: Value1

    // 修改父级字段
    child.Parent.Field2 = 456
    fmt.Println(child.Parent.Field2) // 输出: 456
}
