Struct ElectionState

pub struct ElectionState { /* private fields */ }

A read-only snapshot of durable state for diagnostics and observability.

It makes no liveness, expiry, or leadership-validity claim. Use super::LeaderElection::poll with caller-owned LocalState for protocol decisions instead of deriving authority from this snapshot.

Implementations

impl ElectionState

pub fn owner(&self) -> Option<&ParticipantId>

Returns the durable owner, if the observed state is not released.

Some does not show whether that owner is running or locally renewable.

pub fn rank(&self) -> Rank

Returns the durable revision as a fencing rank.

A rank is retained after resignation so a later acquisition receives a strictly newer fencing epoch.

pub fn lease_duration(&self) -> Option<Duration>

Returns the last persisted lease duration, if this state has been created.

It is historical state, not a persisted expiration deadline.

Trait Implementations

impl Clone for ElectionState

fn clone(&self) -> ElectionState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ElectionState

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

Formats the value using the given formatter.

impl PartialEq for ElectionState

fn eq(&self, other: &ElectionState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
