why StatsUpdateEventArgs is empty class?

[friuns2]

  engine.StatsUpdate += (sender, args) =>
        {
            //log to console
            var statsUpdateEventArgs = (StatsUpdateEventArgs)args;
            
            Console.WriteLine(statsUpdateEventArgs);
        };

I'm trying to log status but it returns nothing because in source its just

namespace MonoTorrent.Client
{
  public class StatsUpdateEventArgs : EventArgs
  {
  }
}

Do i do something wrong here?
