How do I define an async command with a timeout?

[Leonezz]

For io stuff I would like to have commands emited from the web side and executed in rust, but I cannot get the commands be async and timeout if it hangs for too long.

Currently I have tried to make the commands and await in async_std::future::timeout, but it seems the function I passed into async_std::future::timeout never runs.

Here is my code snippet:

#[tauri::command(async)]
pub async fn some_async_command(params: Params) {
  println!("command received"); // <- this is printed
  async_std::future::timeout(Duration::from_secs(5), async {
    println!("async operation start running"); // <- this never prints !!!
    // ... other operation
  }).await
}

Found the issue, it's a deadlock in my code 😄
