Re: Associating data to types

[dom96]

Type cannot be used as values in Nim.

What you should do is something like this:
    
    
    import msgpack4nim
    import strutils
    import typetraits
    
    type
      
      MsgKind = enum
        MsgAlpha, MsgBeta
      
      Msg = object
        id: int
        case kind: MsgKind
        of MsgAlpha:
          x, y: int
          url: string
        
        of MsgBeta:
          resource: string
      
      # ...
    
    const info = {
      MsgAlpha: (id: 1),
      MsgBeta: (id: 2),
      # ...
    }
    
    proc serialize(msg: Msg) =
      var msgcopy = msg
      msgcopy.id = info[msg.kind].id # Too bad!
      echo msgcopy.pack.stringify
    
    serialize Msg(kind: MsgAlpha, x: 10, y: 30, url: "http://foo.bar";)
    serialize Msg(kind: MsgBeta, resource: "GLES2")
    
    
    Run
