Enum ElectionOutcome 

pub enum ElectionOutcome {
    Elected {
        term: u64,
        votes: usize,
        needed: usize,
    },
    ProbeFailed {
        votes: usize,
        needed: usize,
    },
    Lost {
        term: u64,
        votes: usize,

    },
    NotElectable,
    TimedOut {
        votes: usize,
        needed: usize,
    },
}

The result of an election attempt.

Variants

Elected

Won a majority and was promoted under term. votes/needed record the tally (including the candidate’s self-vote).

Fields

term: u64

votes: usize

needed: usize

ProbeFailed

The dry-run probe did not reach a majority, so no term was bumped and no real election was attempted (requirement 1).

Fields

votes: usize

needed: usize

Lost

A real election was attempted (term bumped) but did not reach a majority — e.g. votes split or peers came online between probe and election. The term has advanced; a later attempt stands for a higher term.

Fields

term: u64

votes: usize

needed: usize

NotElectable

The candidate is not electable (a witness, or a catching-up replica, or its own log does not cover the watermark). No probe was sent.

TimedOut

The election ran past its randomized timeout before collecting a majority. No promotion happened.

Fields

votes: usize

needed: usize

Implementations

impl ElectionOutcome

pub fn is_elected(&self) -> bool

Trait Implementations

impl Clone for ElectionOutcome

fn clone(&self) -> ElectionOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ElectionOutcome

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

Formats the value using the given formatter.

impl Eq for ElectionOutcome

impl PartialEq for ElectionOutcome

fn eq(&self, other: &ElectionOutcome) -> 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.
