Struct kube_runtime::scheduler::Scheduler[][src]

pub struct Scheduler<T, R> { /* fields omitted */ }

Implementations

impl<T, R> Scheduler<T, R> where
    T: Eq + Hash + Clone,
    R: Stream<Item = ScheduleRequest<T>>, 
[src]

pub fn hold_unless<C: Fn(&T) -> bool>(
    self: Pin<&mut Self>,
    can_take_message: C
) -> HoldUnless<'_, T, R, C>
[src]

A filtered view of the Scheduler, which will keep items “pending” if can_take_message returns false, allowing them to be handled as soon as they are ready.

The returned HoldUnless is designed to be short-lived: it has no allocations, and no messages will be lost, even if it is reconstructed on each call to poll_next. In fact, this is often desirable, to avoid long-lived borrows in can_take_message’s closure.

NOTE: can_take_message should be considered to be fairly performance-sensitive, since it will generally be executed for each pending message, for each poll_next.
