Method timeout

src/future/future_ext.rs:38–44

Return an error if a future does not complete within a given time span. Typically timeouts are, as the name implies, based on _time_. However this method can time out based on any future. This can be useful in combination with channels, as it allows (long-lived) futures to be cancelled based on some external event. When a timeout is returned, the future will be dropped and destructors will be ru

        Timeout::new(self, deadline.into_future())
    }

    /// Delay resolving the future until the given deadline.
