使用嵌入式结构构造结构文字

Question

How do I construct a struct literal with embedded struct?

Go:

package main

import "fmt"

type Ping struct {
    Content struct {
        name string
    }
}

func main() {
   p := Ping{Content{"hello"}}
   fmt.Println(p)
}

http://play.golang.org/p/UH4YO6CAFv

This works if I had written the structs this way:

Go:

type Ping struct {
   Content
}

type Content struct {
    name string
}

How do I do it with the embedded struct version in the first code version?

Answer 1

You can't, and you really shouldn't either, but if you insist anyway you can use something like:

p := Ping{struct{ name string }{"don't do it"}}

or

p := Ping{}
p.Content.name = "hello"
