Bounded slot validation failures.

Variants

ZeroGeneration

Generation zero is reserved.

UnpublishedSequence

Sequence zero is unpublished.

StaleGeneration

Bound generation differs from shared metadata.

Fields

expected: u64

actual: u64

SequenceWrap

Sequence would wrap.

WrongSlot

Sequence points at a different ring slot.

Fields

expected: u32

actual: u32

UnexpectedFirstSequence

First use of a slot had a noncanonical sequence.

Fields

expected: u64

actual: u64

UnexpectedNextSequence

Reuse was not exactly one ring rotation later.

Fields

expected: u64

actual: u64

MissingAcknowledgement

Reuse lacked an acknowledgement.

Fields

sequence: u64

WrongAcknowledgementTarget

Acknowledgement targets another producer role.

WrongAcknowledgementOwner

Acknowledgement came from another routed owner.

WrongAcknowledgementSlot

Acknowledgement belongs to another producer slot.

WrongAcknowledgementCell

Acknowledgement came from another cell.

StaleAcknowledgementGeneration

Acknowledgement came from another generation.

LaggingAcknowledgement

Acknowledgement lags the exact prior publication.

Fields

expected: u64

actual: u64

FutureAcknowledgement

Acknowledgement attempts to pre-authorize future reuse.

Fields

expected: u64

actual: u64

StaleSequence

Observed sequence differs from expectation.

Fields

expected: u64

actual: u64

PayloadTooLarge

Peer-declared payload exceeds fixed capacity.

Fields

length: u32

capacity: u32

ChangedPayloadLength

Payload length changed during the copy window.

Fields

expected: u32

actual: u32

WrongObservationRole

Observation belongs to another role.

Trait Implementations
