patch

Simplify usage of app event and window label types. The following functions now accept references the Tag can be borrowed as. This means an &str can now be accepted for functions like Window::emit. This is a breaking change for the following items, which now need to take a reference. Additionally, type inference for &"event".into() will no longer work, but &"event".to_string() will. The solution for this is to now just pass "event" because Borrow<str> is implemented for the default event type String.

• Breaking: Window::emit now accepts Borrow for the event.
• Breaking: Window::emit_others now accepts Borrow for the event
• Breaking: Window::trigger now accepts Borrow for the event.
• Breaking: Manager::emit_all now accepts Borrow for the event.
• Breaking: Manager::emit_to now accepts Borrow for both the event and window label.
• Breaking: Manager::trigger_global now accepts Borrow for the event.
• Breaking: Manager::get_window now accepts Borrow for the window label.
• (internal): trait tauri::runtime::tag::TagRef helper for accepting tag references. Any time you want to accept a tag reference, that trait will handle requiring the reference to have all the necessary bounds, and generate errors when the exposed function doesn't set a bound like P::Event: Borrow<E>.
