Struct MenuBarState 

pub struct MenuBarState { /* private fields */ }

The menus of a MenuBar and the one open among them.

Owned by the view that shows the bar, which observes it so a change renders. The open menu is a MenuState, so its keyboard, dismissal, and focus are every menu’s: Left and Right at its root move to the neighbouring menu. Items’ actions go to the element that had focus before the bar opened, so Edit > Copy reaches the focused field.
