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Sequence zero is unpublished.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

Bound connection generation.

actual: u64

Generation observed in shared metadata.

SequenceWrap

Sequence would wrap.

WrongSlot

Sequence points at a different ring slot.

Fields

expected: u32

Slot selected by the publication sequence.

actual: u32

Slot supplied by the caller or observation.

UnexpectedFirstSequence

First use of a slot had a noncanonical sequence.

Fields

expected: u64

Canonical first sequence for the slot.

actual: u64

Requested first sequence.

UnexpectedNextSequence

Reuse was not exactly one ring rotation later.

Fields

expected: u64

Exact next sequence after one ring rotation.

actual: u64

Requested reuse sequence.

MissingAcknowledgement

Reuse lacked an acknowledgement.

Fields

sequence: u64

Prior sequence that must be acknowledged before reuse.

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

Exact prior publication sequence required for reuse.

actual: u64

Older acknowledged sequence supplied by the caller.

FutureAcknowledgement

Acknowledgement attempts to pre-authorize future reuse.

Fields

expected: u64

Exact prior publication sequence required for reuse.

actual: u64

Future acknowledged sequence supplied by the caller.

StaleSequence

Observed sequence differs from expectation.

Fields

expected: u64

Sequence requested by the reader.

actual: u64

Sequence observed in shared metadata.

PayloadTooLarge

Peer-declared payload exceeds fixed capacity.

Fields

length: u32

Peer-declared payload length.

capacity: u32

Validated fixed payload capacity.

ChangedPayloadLength

Payload length changed during the copy window.

Fields

expected: u32

Payload length captured before the copy.

actual: u32

Payload length observed during the recheck.

WrongObservationRole

Observation belongs to another role.

Trait Implementations
