Rejected election event. Missing history/quorums wait; conflicts fault.

Variants

Replication(ReplicationError)

Existing journal/normal scope, role, or membership check failed.

ViewNotHigher

Timers/messages cannot regress or reuse the target view.

ViewExhausted

A restart cannot safely wrap its highest durable view back to zero.

StoragePending

All accepted old-view operations must finish synchronization first.

PromisePending

Only one metadata promise action can be in flight.

AlreadyPromised

No new metadata write is necessary for this requested view.

StalePromise

Completion is not the exact outstanding metadata action.

PromiseRequired

No election message before successful durable promise completion.

StartQuorumMissing

Need own durable promise plus another distinct first-phase voter.

ReportQuorumMissing

Selection needs the primary’s own report and another distinct voter.

HistoryMissing

Fetch and validate the frozen selected history before selecting it.

InvalidReport

Malformed positions or last-normal-view cannot become evidence.

ConflictingHistory

A protected prefix or immutable report conflicts with this lineage.

SelectionFrozen

Do not change the selected quorum while installation may be in flight.

SelectionRequired

Primary cannot install without its completed quorum selection.

ReusedGeneration

A replacement writer needs a fresh, globally unique incarnation.

StaleInstallation

Completion does not identify this exact pending installation.

InstallationCompleted

Successful completion has already transferred ownership to a new role.

ApplicationPending

Committed canonical state must be rebuilt before role activation.

Faulted

Storage or lineage fault requires recovery, not another local election.

impl Eq for ViewChangeError

impl Error for ViewChangeError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
