Enum Outcome 

pub enum Outcome<V>
where
    V: Identities,
{
    Transferred(u32),
    Failed(IoFault),
    NeverIssued {
        abandoned: Epoch<V>,
    },
}

How a consumer operation ended.

Variants

Transferred(u32)

Completed, with the count its completion reported. A write never completes short: its target completes it in full or with a fault (DI-D-50); a read may.

Failed(IoFault)

The operation reached its target and failed, as the backend reported it.

NeverIssued

A gated operation an abandoned epoch stopped before it was released: it never reached the kernel, so nothing was written. The epoch was its gate, or – for a write – its own, which no write may join once abandoned (DI-D-35, DI-D-43).

Fields

abandoned: Epoch<V>

The abandoned epoch that stopped it: its gate if that was abandoned, else its own.
