7011 :: Is there a way for case objects to have cases share fields?

  I want both nkDocument and nkCanvas to have children, but not nkRectangle? Is there a way to do this?

  type
    NodeKind = enum
      nkDocument
      nkCanvas
      nkRectangle
    
    Node = ref object
      case kind: NodeKind
      of nkDocument:
        children: seq[Node]
      of nkCanvas:
        children: seq[Node]
      of nkRectangle:
        box: Rect
  Run

  I also tried nkDocument, nkCanvas, but I need nkCanvas to eventually be different from document?

  
    Node = ref object
      id: string
      name: string
      case kind: NodeKind
      of nkDocument, nkCanvas:
        children: seq[Node]
      of nkCanvas:
        backgroundColorColor: Color
        prototypeStartNodeID: string
      of nkRectangle:
        box: Rect
  Run
