Function use_update

Source
pub fn use_update<'hook>() -> impl 'hook + Hook<Output = Rc<dyn Fn()>>
Expand description

A hook returns a function that forces component to re-render when called.

§Example

use yew_hooks::prelude::*;

#[function_component(Update)]
fn update() -> Html {
    let update = use_update();

    let onclick = Callback::from(move |_| {
        update();
    });
    
    html! {
        <>
            <button {onclick}>{ "Update" }</button>
        </>
    }
}

§Note

When used in function components and hooks, this hook is equivalent to:

pub fn use_update() -> Rc<dyn Fn()> {
    /* implementation omitted */
}
