Decoding with root object

[dunyakirkali]

I'm trying to decode a json object which has a root object.

So basically my json looks like this:

"Id": {
  "id": 1561
}

And when I parse it with Poison I would like to get

%Id{id: 1561} == Poison.decode!("\"Id\":{\"id\":1561}", %Id{})

where Id is:

defmodule Id do
  @derive [Poison.Encoder]
  defstruct [:id]
end

I couldn't find a way to deal with root object. Is that possible?
