[erlang-questions] untyped records

[Karolis Petrauskas]

Hi,

     Its a proplist wrapped to a {struct, _}. You can access its
fields as follows:
{struct, X} = {struct,[
         {code,1372793577767},
         {desc,"e7iOSxy6PYQiMRk87r5cHK4DVAUj5SzI"},
         {units,"g|Kg"}
]}.
proplists:get_value(desc, X).
