Function with_state

pub fn with_state<S, T, V>(
    build: impl FnOnce() -> S + 'static,
    view: impl FnMut(&mut S, &mut T) -> V + 'static,
) -> WithState<S, T, V>
where
    V: View<(S, T)>,

Create a new WithState.

Example

struct Data {
    // ...
}

fn ui() -> impl View<Data> {
    with_state(
        || 0,
        |count, _data| {
            on_click(
                button(text!("Clicked {} time(s)", count)),
                |cx, (count, _data)| {
                    *count += 1;
                    cx.rebuild();
                },
            )
        }
    )
}
