Function freya::prelude::use_future

pub fn use_future<F>(future: impl FnMut() -> F + 'static) -> UseFuture
where
    F: Future + 'static,

A hook that allows you to spawn a future. This future will not run on the server The future is spawned on the next call to wait_for_next_render which means that it will not run on the server. To run a future on the server, you should use spawn directly. use_future won’t return a value. If you want to return a value from a future, use use_resource instead.

fn app() -> Element {
    let mut count = use_signal(|| 0);
    let mut running = use_signal(|| true);
    // `use_future` will spawn an infinitely running future that can be started and stopped
    use_future(move || async move {
        loop {
           if running() {
               count += 1;
           }
           tokio::time::sleep(Duration::from_millis(400)).await;
       }
    });
    rsx! {
        div {
            h1 { "Current count: {count}" }
            button { onclick: move |_| running.toggle(), "Start/Stop the count"}
            button { onclick: move |_| count.set(0), "Reset the count" }
        }
    }
