Struct tokio::runtime::coop::Coop

pub(crate) struct Coop<F: Future> {
    pub(crate) fut: F,
}

Future wrapper to ensure cooperative scheduling.

When being polled poll_proceed is called before the inner future is polled to check if the inner future has exceeded its budget. If the inner future resolves, this will automatically call RestoreOnPending::made_progress before resolving this future with the result of the inner one. If polling the inner future is pending, polling this future type will also return a Poll::Pending.

Fields

fut: F

Trait Implementations

type Output = <F as Future>::Output

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
