Create generic struct fields inside a struct and initial in go

How to create a struct with generic struct inside and init it in go ,
I see similar question here https://stackoverflow.com/questions/68166558/generic-structs-with-go but the fields is primitive type , I need the field of struct is generic and set this field as other struct

I try but it not work

type ResponseData[T struct{}] struct {
	status          int
	error           string
	soaErrorCode    string
	soaErrorDesc    string
	clientMessageId string
	path            string
	data            T
}

And I try to init it

    message := struct {
		accountId string
	}{
		accountId: "0344561299",
	}
	bodyin := RoutinQueryInput[struct{}]{
		Destination: "AAA-BBB",
		Version:     "1.2",
		Message:     message,
	}

It said :

> Cannot use 'message' (type struct {...}) as the type struct{}

In Java, we can create object generic inside a object , how to do that in go?

If your type parameter list says [T struct{}], that means type T can only be struct{}. That doesn't mean that it can be any struct type, it literally means struct{} (the empty struct).

There's no type constraint that means "all types which are structs". Even if there was, it wouldn't do you any good, because it doesn't describe any common behaviour.

You should change it to be type ResponseData[T any] so that the data field can be of any type.

It will also be more convenient if you declare your message type as a named type, so you can reference it on instantiation. For example:

    type messageType struct {
        accountId string
    }
    message := messageType{
        accountId: "0344561299",
    }
    bodyin := RoutinQueryInput[messageType]{
        Destination: "AAA-BBB",
        Version:     "1.2",
        Message:     message,
    }
