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?
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"
This doesn't seem to be supported, looking at the spec for Struct type
A field declared with a type but no explicit field name is an anonymous field, also called an embedded field or an embedding of the type in the struct.
An embedded type must be specified as a type name T or as a pointer to a non-interface type name *T, and T itself may not be a pointer type.
That means T must be defined somewhere else.
