Struct Shell 

pub struct Shell { /* private fields */ }

Implementations

impl Shell

pub fn builder(app_id: &str) -> ShellBuilder

app_id: lowercase letters, digits and - (it names the single-instance service and the LaunchAgent / registry entry), at most 40 characters.

impl Shell

pub fn single_instance_plugin( self, on_second_instance: impl Fn(&AppHandle<Wry>, &[String], &str) + Send + Sync + 'static, ) -> TauriPlugin<Wry>

Install single-instance arbitration only. Add this plugin FIRST. Only the builder’s app_id is used; arbitration is always enabled. The callback receives forwarded argv & cwd and owns all second-launch behavior. No script, navigation policy, window state, presence loop or ShellState is installed. Keep using the app’s own invoke handler; handler! requires the full shell.

pub fn lifecycle_plugin(self) -> TauriPlugin<Wry>

The shell’s lifecycle without its webview policy: single instance, close behaviour, tray, menu, second-launch routing, deep links, quit and the commands, but no hardening init script or native hardening, no navigation policy, no presence thread, no watchdog and no window-state restore or save. The same as ShellPlugin::builder().shell(self).lifecycle_only(). Shell::plugin is unchanged.

pub fn plugin(self) -> TauriPlugin<Wry>

The single Tauri plugin that installs the whole shell, with every module enabled. Add it FIRST so single-instance arbitration runs before any other plugin does work. To opt modules out, use ShellPlugin::builder.
