Loading bar when doing computation on the backend?

[0ctopirate]

When trying to do large computation on the backend, it would be nice to display the status of the loop, but I'm not sure how you'd go about this. Maybe you could try to use generators?

Also, when the program is alt-tabbed and the backend is doing computation, you can't tab back into it. Is there any way to fix this?

You could emit events from inside your commands to report the current progress. Here's a slightly more complicated example (because it uses streams) from one of our plugins: https://github.com/tauri-apps/tauri-plugin-upload/blob/dev/src/lib.rs#L73

You can try making your command async so that it doesn't run on the main thread.
