pub struct Callback<In, Out = ()>(/* private fields */)
where
In: 'static,
Out: 'static;
Expand description
Callbacks define a standard way to store functions and closures.
§Example
#[component]
fn MyComponent(
#[prop(into)] render_number: Callback<i32, String>,
) -> impl IntoView {
view! {
<div>
{render_number.call(42)}
</div>
}
}
fn test() -> impl IntoView {
view! {
<MyComponent render_number=move |x: i32| x.to_string()/>
}
}
