How to open "dialog with message" from Rust?

[EGSP]

I want to show error message from Rust to explain problem to user. Now im using panic, but it just crashes app, as expected i think.

I dont understand Tauri API docs. Moreover, it seems that Tauri API shows JavaScript frontend code.

Can someone show example of code which function and how to call from Rust?

The rust documentation is on docs.rs: https://docs.rs/tauri/latest/tauri/api/dialog/fn.message.html / https://docs.rs/tauri/latest/tauri/api/dialog/blocking/fn.message.html

The docs are generally stil lacking but in this case i think there isn't that much to show. Here's an in-code example (for ask but message is almost the same)

tauri/examples/api/src-tauri/src/main.rs

Lines 224 to 236 in b02fc90

	ask(
	Some(&window),
	"Tauri API",
	"Are you sure that you want to close this window?",
	move |answer| {
	if answer {
	// .close() cannot be called on the main thread
	std::thread::spawn(move || {
	app_handle.get_window(&label).unwrap().close().unwrap();
	});
	}
	},
	);

When to use blocking dialog?

[FabianLars]

Basically only in async tauri commands (or async functions in general). non-async commands, and the Builder's hooks (like .setup) will run on the main thread which will require the non-blocking dialog.

Thank you for clarification!

What should i do to enable dialogs api in my project?

Nevermind, found answer in JavaScript Tauri api
