nit: a BooleanCallback like this should only be used in situations where you
want to get a piece of information that is a boolean, like chrome.foo.getBar(). 

For indicating success or failure, you should just return true or false from
your ExtensionFunction, and the callback in JS should just examine
chrome.runtime.lastError.

So for example:



callback VoidCallback = void();

interface Functions {
  static void doSomething(VoidCallback callback);
}

Done.

   callback ItemsInfoCallback = void (ItemInfo[] result);
   callback GetStringsCallback = void (object result);
   callback PathCallback = void (DOMString path);
   callback PackCallback = void (PackDirectoryResponse response);
 
   interface Functions {
     // Runs auto update for extensions and apps immediately.
     // |callback| : Called with the boolean result, true if autoUpdate is
     // successful.
     static void autoUpdate(BooleanCallback callback);
