Long running async task

[MTRNord]

Hi I have an API that requires polling to get updates. I am aware about Command::perform for short term async execution. How could I however integrate with never exiting async execution?

This specifically would be https://matrix-org.github.io/matrix-rust-sdk/matrix_sdk/struct.Client.html#method.sync for my case or https://matrix-org.github.io/matrix-rust-sdk/matrix_sdk/struct.Client.html#method.sync_with_callback

the first one emits it data to a struct implementing a specific trait or the second one is just a callback which actually is a loop internally.

So I need either of these hooked in a way where I can trigger the UI to update. Any ideas on how to archive this?

I have also seen Subscriptions but I am honestly not sure how to use them or if they work with this at all :) I can certainly add my Messagges I want to emit to a list and from that maybe for am a Subscription. But to get there I would need some help on how to do it correct/efficent in this case :)

Does this help?

Thinking about this myself, I wonder if Subscription might be suitable.

I notice the stopwatch example uses it to update as time elapses.

It seems like you can create your own subscription by implementing a Recipe and using Subscription::from_recipe...

If you get anywhere with this, let me know :D

The Recipe docstring also links to the stopwatch and download progress examples, so those two might help
