Re: Fast marshalling / serialisation system

["Wim Couwenberg" <wim.couwenberg@...>]

David, you could also consider to construct the item directly on the
other stack, instead of marshalling.  Here's the rough idea:

/* copy object from one universe to another.
  both universes must be locked during this
  copy operation. */
void copy(lua_State *to, lua_State *from, int index)
{
 switch (lua_type(from, index))
 {
   case LUA_TNIL:
     lua_pushnil(to);
     break;

   case LUA_TNUMBER:
     lua_pushnumber(to, lua_tonumber(from, index));
     break;

   case LUA_TSTRING:
     lua_pushstring(to, lua_tostring(from, index));
     break;

   ...
 }
}


The LUA_TTABLE case is the most difficult, but not too hard, depending
on how advanced you want to make it.
