pub trait Task: Future<Output = ()> {
#[must_use]    pub fn cancel<'async_trait>(
        self: Box<Self>
    ) -> Pin<Box<dyn Future<Output = Option<()>> + 'async_trait>>
    where
        Self: 'async_trait;
}

A common interface to wait for a Task completion, let it run n the background or cancel it.

Required methods

#[must_use]pub fn cancel<'async_trait>(
    self: Box<Self>
) -> Pin<Box<dyn Future<Output = Option<()>> + 'async_trait>> where
