One entry of the instance’s completion queue (DI-D-13).

Variants

Op(OpCompletion<V, B, C>)

A consumer operation completed.

Durable

The high-water mark of through’s lineage has reached it.

Fields

through: Epoch<V>

The epoch reached.

Failed(Failed<V>)

A durability failure was observed.

Blocked

A request’s flushes succeeded, but an unresolved failure at or below through prevents reporting it. Fixed-size and allocation-free, so producing it is cheap.

Fields

through: Epoch<V>

The request’s epoch.

by: <V as Identities>::FailureId

The failure in the way.

Abandoned

The consumer abandoned a failure: its final record.

Fields

failure: <V as Identities>::FailureId

The failure abandoned.

suspect: SuspectSet<V>

Its suspect set, now declared lost.

markings: Vec<Marking<V>>

Every marking it gained up to this resolution, in the order observed. A suspect write still in flight now is reported only by its own completion (DI-D-47).

Healed

A heal took effect (DI-D-12 (c)): the failure is resolved as healed, and this is its final record.

Fields

failure: <V as Identities>::FailureId

The failure healed.

suspect: SuspectSet<V>

Its suspect set.

markings: Vec<Marking<V>>

Every marking it gained up to this resolution, in the order observed. A suspect write still in flight now is reported only by its own completion (DI-D-47).

Marked

A failure not yet resolved gained a marking.

Fields

failure: <V as Identities>::FailureId

The failure.

marking: Marking<V>

The marking.

LineageEnded

end_lineage took effect: every epoch of lineage not yet durable, through abandoned_through, is abandoned (None if none was pending).

Fields

lineage: <V as Identities>::Lineage

The lineage ended.

abandoned_through: Option<<V as Identities>::EpochId>

The highest id abandoned, if any was.

Trait Implementations

where V: Debug + Identities, B: Debug, C: Debug, <V as Identities>::FailureId: Debug, <V as Identities>::Lineage: Debug, <V as Identities>::EpochId: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
