synchronous execution in a tokio::spawn

[setoelkahfi]

I spawned a new thread with tokio::spawn and some asynchronous tasks. Like so:

    fn prepare_result_files(app: tauri::AppHandle, audio_file_id: i32, results: Vec<ResultFile>) {
        debug!("Preparing result files: {:?}", audio_file_id);
        let id = audio_file_id.to_string();
        tokio::spawn(async move {
            save_result_files(&id, &results).await;
            download_result_files(&id, results).await;
            prepare_tracks();
            prepare_players(&id).await;
            let _ = app.emit_all(PLAYER_IS_READY, audio_file_id);
        });
    }

The problem is that the emil_all event sometimes gets executed before all the await tasks are finished. I want to perform the functions inside the spawn synchronously so that the code emits PLAYER_IS_READY event correctly. I have looked at the spawn_blocking one, but I don't think that's what I need.

Any pointers?

Async/await executes operations one line at the time, so emit_all does not get called before the .await operations before it finish.

Ok, I think this is a bug somewhere else. Thanks for the reply @Darksonn
