Enum MenuRole 

pub enum MenuRole {
    Cut,
    Copy,
    Paste,
    SelectAll,
    Undo,
    Redo,
    Delete,
    About,
    Quit,
    Preferences,
    Minimize,
    CloseWindow,
    Fullscreen,
    NewWindow,
    CheckForUpdates,
}

A standard/system command. The backend supplies the native item, a selector on AppKit/UIKit (cut:/copy:/paste:…) or a stock action on GTK/Qt/XAML, so it targets the focused control, gets the platform’s default label + shortcut, and enables/disables itself automatically. This is how default items (Edit ▸ Cut/Copy/Paste, the app’s Quit/About) are accommodated without the app re-implementing them.

Variants

Cut

Copy

Paste

SelectAll

Undo

Redo

Delete

About

The app’s About command (docs/settings.md). With an About registered through day::register_about the item lowers to that dispatch action (a Day-rendered About window, or the toolkit’s own About dialog where one exists); without one AppKit shows its stock Info.plist panel and the other desktops show the label alone.

Quit

Preferences

Minimize

CloseWindow

Fullscreen

NewWindow

File ▸ New Window (docs/windows.md): opens another window through the builder the app registered with day::register_new_window. No platform has a native selector for it, so the item lowers to the registered dispatch action (disabled when none).

CheckForUpdates

Check for Updates… (docs/settings.md): placed directly under About in the macOS App menu (the Sparkle convention) and in Help elsewhere. Lowers to the action an updater registered with day::register_check_for_updates; absent from the bar when none did.
