Lua-Sqlite3 set a timeout or set a handler?

The document said, "In Sqlite3 there are two ways to deal with locked databases. You can set a timeout or set a handler."
So If I set a timeout then I couldn't set a handler. Versa vice If I set a handler then I couldn't set a timeout,
Do I understand it correctly?
