This is to allow:

IndexedDBDatabaseError error;
if (...)
  error = IndexedDBDatabaseError(...);
else
  error = IndexedDBDatabaseError(...);
callbacks->DoIt(error);

... which seemed to be the most readable, but I'm open to alternatives.

   IndexedDBDatabaseError(uint16 code, const char* message)
       : code_(code), message_(base::ASCIIToUTF16(message)) {}
   IndexedDBDatabaseError(uint16 code, const base::string16& message)
       : code_(code), message_(message) {}
   ~IndexedDBDatabaseError() {}
 
   uint16 code() const { return code_; }
   const base::string16& message() const { return message_; }
 
  private:
-  const uint16 code_;
-  const base::string16 message_;
-
-  DISALLOW_COPY_AND_ASSIGN(IndexedDBDatabaseError);
+  uint16 code_ = 0;
+  base::string16 message_;
 };
