Enum MenuBarRole 

#[non_exhaustive]
pub enum MenuBarRole {
    File,
    Edit,
    View,
    Settings,
    Window,
    Help,
}

A standard menu-bar slot (macOS’s File/Edit/View/Window/Help, and their counterparts elsewhere). A backend that has a house style for the menu bar fills every slot an app did not claim with its own stock menu, so an app never has to restate the platform’s furniture — and can still replace any of it by tagging its own submenu with the matching role.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

File

Edit

View

Settings

KDE/Plasma’s Settings menu (Configure , Configure Shortcuts). No counterpart on macOS, where preferences live in the app menu, or on GNOME/Windows.

Window

macOS’s Window menu. Windows and Linux desktops do not have one.
