Struct Builder 

pub struct Builder<R: Runtime> { /* private fields */ }

Builds the single-instance plugin.

Created with Builder::new and consumed by Builder::build.

Implementations

impl<R: Runtime> Builder<R>

pub fn new() -> Self

Creates a new builder with a no-op callback (or, when the deep-link feature is enabled, a callback that only forwards the arguments to the deep-link plugin) and no custom D-Bus ID. Use Builder::callback and Builder::dbus_id to configure it, then Builder::build to create the plugin.

pub fn callback<F: FnMut(&AppHandle<R>, Vec<String>, String) + Send + Sync + 'static>( self, f: F, ) -> Self

Function to call when a secondary instance was opened by the user and killed by the plugin. If the deep-link feature is enabled, the plugin triggers the deep-link plugin before executing the callback.

pub fn dbus_id(self, dbus_id: impl Into<String>) -> Self

Set a custom D-Bus ID, used on Linux. The plugin will append a .SingleInstance subname. For example com.mycompany.myapp will result in the plugin registering its D-Bus service on com.mycompany.myapp.SingleInstance. Usually you want the same base ID across all components in your app.

Defaults to the app’s bundle identifier set in tauri.conf.json.

pub fn build(self) -> TauriPlugin<R>

Builds the single-instance TauriPlugin.

Register it first among your app’s plugins, since the plugins run in the order they were added and a second instance must be detected before the rest of your setup runs.

Trait Implementations

impl<R: Runtime> Default for Builder<R>

fn default() -> Self

Returns the “default value” for a type.
