How to await inside tauri main_window.listen("tauri://close-requested")

How to run async fn and await them inside tauri listen closure ?

[open breach]

if you mean awaiting its completion and/or getting back a value that you want to use in the rest of the listen closure then i think this is not possible 🤔

or actually, nevermind. Since the listen closure is a callback anyway you could turn the whole closure into an async function

[torpid ice]

Well, I need to listen to this event in rust side

[open breach]

ohhh, you're talking about the rust side

nevermind then

tauri://close-requested is javascript only, on rust you need to use the .on_window_event() or .run()

and then you can use async_runtime::block_on(async_task) to run the async function.

I use tokio and got this error

thread 'main' panicked at 'Cannot start a runtime from within a runtime. This happens because a function (like `block_on`) attempted to block the current thread while the thread is being used to drive asynchronous tasks.', /Users/user/.cargo/registry/src/github.com-1ecc6299db9ec823/tauri-1.2.4/src/async_runtime.rs:208:27

I think I need to use tokio::spawn instead of async_runtime::block_on

am I right ?

[open breach]

spawn won't wait for the task to finish so the app may close before its done

are you using #[tokio::main]?

because normally it shouldn't throw that error in this context

Yes, I use #[tokio::main]

And I share the current runtime with Tauri via
tauri::async_runtime::set(tokio::runtime::Handle::current());

[torpid ice]

I used

tokio::task::block_in_place(move || {
    tokio::runtime::Handle::current().block_on(async move {
        // Code here
    })
});

Without any issue
