Function freya::prelude::use_shared_state_provider

pub fn use_shared_state_provider<T>(cx: &ScopeState, f: impl FnOnce() -> T)where
    T: 'static,

Provide some state for components down the hierarchy to consume without having to drill props. See use_shared_state to consume the state

Example

#[derive(Clone, Copy)]
enum Theme {
    Light,
    Dark,
}

// Provider
fn Parent<'a>(cx: Scope<'a>) -> Element<'a> {
    use_shared_state_provider(cx, || Theme::Dark);
    let theme = use_shared_state::<Theme>(cx).unwrap();

    render! {
        button{
            onclick: move |_| {
                let current_theme = *theme.read();
                *theme.write() = match current_theme {
                    Theme::Dark => Theme::Light,
                    Theme::Light => Theme::Dark,
                };
            },
            "Change theme"
        }
        // Children components that consume the state...
    }
}
