Function serenity_utils::menu::prev_page

pub async fn prev_page<'_, '_>(menu: &'_ mut Menu<'_>, reaction: Reaction)

Note: This function is not a ControlFunction. To turn it into a control function, you must pin it and then create an Arc of it.

let prev_page_cfn = Arc::new(|m, r| Box::pin(prev_page(m, r)));

prev_page_cfn is a ControlFunction and can be used to control a menu.
