How to dynamically initialize a global variable in gpui?

[so1ve]

Hello everyone! I'm a rust beginner and I just started to use gpui to build my own tool.

Here is my code snippet:

pub struct State {
    client: Option<SrunClient>,
}

app.run(move |cx| {
    cx.set_global(State {
        client: None,
    });

    cx.background_executor().spawn(async move {
        let client = SrunClient::new(username, password, Some(Client::new()), None, None)
            .await
            .unwrap();
        cx.update_global::<State, ()>(|state, _| {
            state.client = Some(client);
        });
    });
}）

You can see that the initialization step of SrunClient is asynchronous. However my code is not working because cx violates borrowing rules; I tried cx.spawn() also but tokio just panicked.

Is there any way to achieve this? Thanks in advance!

Not only the init code is async, it's not on the main thread, on a background thread — there's no UI on that thread, hence no cx.
Instead, cx.spawn should be used.

Thank you!
