Enum Unparked 

Source 
pub enum Unparked<M: Manage> {
    Claimed(M::Connection, SlotMeta),
    Empty,
    Lost,
}
Expand description

What an Exchange produced for Exchange::unpark.

Variants§

§

Claimed(M::Connection, SlotMeta)

Claimed from another thread and re-wrapped in this thread’s runtime.

§

Empty

Nothing was available; the caller should dial.

§

Lost

One was taken, but Detach::attach failed and it has been destroyed. The caller should dial. Reported separately so the pool can keep its created/closed counters balanced.
