Enum MenuBarStyle 

#[non_exhaustive]
pub enum MenuBarStyle {
    Macos,
    Gnome,
    Kde,
    Windows,
}

Arrange an app’s top-level menus into the platform’s standard bar, filling every standard slot the app did not claim with the backend’s stock menu.

Which desktop’s menu-bar conventions a backend follows. A toolkit picks the style of the platform it is native to, not the one it happens to be compiled on.

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.

Macos

macOS: an app menu, and a Window menu the toolkit installs natively.

Gnome

GNOME / GTK on Linux.

Kde

KDE Plasma / Qt on Linux.

Windows

Windows.

Implementations

impl MenuBarStyle

pub fn bar_order(self) -> (&'static [MenuBarRole], &'static [MenuBarRole])

The standard slots before and after the app’s own menus on this desktop.

pub fn stock(self, role: MenuBarRole) -> Option<MenuItem>

This desktop’s stock menu for a slot, as a pure model: every entry is a MenuRole, so each backend renders it with its own native command and localized label and nothing here is toolkit- or app-specific.

File is always the app’s own. Window is None even on macOS because the toolkit installs it natively (only AppKit can append the live window list). Settings is None for now everywhere: Preferences is placed before a backend sees the model (inject_preferences), so a stock Settings menu would be a second copy of it.

Trait Implementations

impl Clone for MenuBarStyle

fn clone(&self) -> MenuBarStyle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MenuBarStyle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MenuBarStyle

fn eq(&self, other: &MenuBarStyle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
