Enum RefusalReason 

pub enum RefusalReason {
    WatermarkNotCovered {
        candidate_lsn: u64,
        watermark: u64,
    },
    AlreadyVoted {
        term: u64,
        voted_for: String,

    StaleTerm {
        candidate_term: u64,
        voter_term: u64,
    },
}

Why a voter refused a candidate.

Variants

WatermarkNotCovered

The candidate’s log does not cover the commit watermark, so an acknowledged synchronous write could be lost — the safety core refuses (requirement 3).

Fields

candidate_lsn: u64

watermark: u64

AlreadyVoted

The candidate’s term is not newer than a term this voter already participated in, and the voter already granted that term to someone else (durable double-vote guard, requirement 2).

Fields

term: u64

voted_for: String

StaleTerm

The candidate’s term is older than the voter’s current term — a stale candidate from a superseded term.

Fields

candidate_term: u64

voter_term: u64

Trait Implementations

impl Clone for RefusalReason

fn clone(&self) -> RefusalReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RefusalReason

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

Formats the value using the given formatter.

impl Eq for RefusalReason

impl PartialEq for RefusalReason

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