Struct NavBarAction 

pub struct NavBarAction {
    pub action: u64,
    pub label: String,
    pub icon: Option<String>,
}

A trailing action button on the navigation bar (docs/navigation.md) — the phones’ and HarmonyOS’s stand-in for a desktop toolbar button, since those toolkits have no window toolbar (Cap::Toolbar is Unsupported). Rendered upper-right on the nav bar by the mobile backends (iOS rightBarButtonItem, Android/HarmonyOS a menu action); ignored by desktop split presentations, which carry their commands in a real toolbar instead.

action is a menu-action dispatch id (register_menu_action): the backend emits Event::MenuAction(action) when the button is tapped, and the tree runs the registered closure. icon is a bundled image name (resolved via resolve_image_file, the same convention as NavMenuProps::icons); label is its accessible name and tooltip.

Fields

action: u64

label: String

icon: Option<String>
