go struct representation of Ellipsis (arbitrary fields)

[sjwl]

if

type Foo struct {
  Name *string `cue: ""`
}

is equivalent to

#Foo: {
  Name?: null | string @go(Type,*string)
}

what is the go equivalent to

#Foo: {
  Name?: null | string @go(Type,*string)
  ...
}

I guess, it's not possible to represent an arbitrary field with a go struct? I am curious as well how it could be written in golang.
