Destroying a Window

To close a Window, it must be destroyed using the destroy method:

window.destroy

When a Window is destroyed, the GLFWwindow pointer that it encapsulates become obsolete. If you attempt to use a Window for some purpose after it has been destroyed, either an exception will be raised or some undefined behavior will occur. For this reason, never use a destroyed window! Make sure that destroy is the last method used on a Window object in your application logic and you'll be golden.

destroy must be called from within a run block definition.
