Hi, thanks for this great example on how to use Tokio together with egui. It helps a lot. But I also have something in mind:

This line of code spawns a new std thread and execute some blocking async code inside. Your comments above that indicates the purpose is to execute the runtime in its own thread. But I think this is unnecessary because tokio::runtime::Runtime::new() itself creates a multi-threaded scheduler.

However, if we switch to tokio::runtime::Builder::new_current_thread().enable_all().build() while creating the runtime, a single-threaded executor will be created, thus we need to spawn another std thread for runtime execution.

Please point out my mistakes if any. Thank you!

Hey, any idea how you would implement this for a websocket connection? I'd like to pass some messages from the websocket connection in a separate thread to the the GUI in the main thread, so it can plot some values from the websocket connection. How would I go about doing this?

Also, in the send_req function, where does the spawned thread live? I'm having some trouble understanding that, since i thought u'd have to spawn the thread in the main.rs main function
