Function use_unmount

pub fn use_unmount<'hook, Callback>(
    callback: Callback,
) -> impl 'hook + Hook<Output = ()>
where
    Callback: FnOnce() + 'static + 'hook,

A lifecycle hook that calls a function when the component will unmount.

Example

use yew_hooks::prelude::*;

#[function_component(Unmount)]
fn unmount() -> Html {
    use_unmount(|| {
        debug!("Running clean-up of effect on unmount");
    });
    
    html! {
        <>
        </>
    }
}

Note

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

pub fn use_unmount<Callback>(callback: Callback)
where
    Callback: FnOnce() + 'static,
{
    /* implementation omitted */
}
