Struct DefaultPostRoot 

pub struct DefaultPostRoot(pub Rc<dyn Fn(&mut WidgetTree, WidgetId) -> WidgetId>);

Closure that runs after each window’s root_builder returns, wrapping the user’s root widget. Stored in app_state so it is shared across every window the app opens at runtime.

The closure may be invoked from many windows over the app’s lifetime — it receives &mut WidgetTree and the user’s root id, and returns the id of the (possibly wrapped) widget to use as the window’s effective root.
