Go语言中Struct与继承与匿名字段和内嵌结构体全面详解

type Person struct {
    name string
    age int
    sex string
}
func (Person) SayHello(){
 fmt.Println("this is from Person")
}
type Student struct {
    Person
    school string
}
func main() {
    stu := Student{school:"middle"}
    stu.name = "leo"
    stu.age = 30
    fmt.Println(stu.name) //这里其实就是这样做了一层转换stu.Person.name
    stu.SayHello() //也做了转换
}

package main
import "fmt"
type innerS struct {
    in1 int
    in2 int
}
type outerS struct {
    b    int
    c    float32
    int  // anonymous field
    innerS //anonymous field
}
func main() {
    outer := new(outerS)
    outer.b = 6
    outer.c = 7.5
    outer.int = 60
    outer.in1 = 5
    outer.in2 = 10
    fmt.Printf("outer.b is: %d\n", outer.b)
    fmt.Printf("outer.c is: %f\n", outer.c)
    fmt.Printf("outer.int is: %d\n", outer.int)
    fmt.Printf("outer.in1 is: %d\n", outer.in1)
    fmt.Printf("outer.in2 is: %d\n", outer.in2)
    // 使用结构体字面量
    outer2 := outerS{6, 7.5, 60, innerS{5, 10}}
    fmt.Println("outer2 is:", outer2)
}

package main
import "fmt"
type A struct {
    ax, ay int
}
type B struct {
    A
    bx, by float32
}
func main() {
    b := B{A{1, 2}, 3.0, 4.0}
    fmt.Println(b.ax, b.ay, b.bx, b.by)
    fmt.Println(b.A)
}

type A struct {a int}
type B struct {a, b int}
type C struct {A; B}
var c C

type D struct {B; b float32}
var d D
