Struct QuorumPolicy 

pub struct QuorumPolicy {
    pub n: usize,
    pub w: usize,
    pub ack_timeout: Duration,
    pub clock_skew_warn: Duration,
}

Operator-tunable quorum policy. See ADR-0001 § Model for the complete contract.

Fields

n: usize

Total peer count — local node + remotes. Must be >= 1.

w: usize

Required acks including the local commit. Clamped to [1, n] at construction via QuorumPolicy::new.

ack_timeout: Duration

Deadline for the remote-ack collection phase. Times out with QuorumError::QuorumNotMet { reason: Timeout }.

clock_skew_warn: Duration

Warning threshold for peer clock skew. Exceeding this does not fail the quorum; it surfaces in the clock-skew histogram.

Implementations

impl QuorumPolicy

pub fn new( n: usize, w: usize, ack_timeout: Duration, clock_skew_warn: Duration, ) -> Result<Self, QuorumError>

Construct a quorum policy. w is clamped to [1, n] and n = 0 is rejected as invalid input.

Errors

Returns QuorumError::InvalidPolicy if n == 0.

pub fn majority(n: usize) -> Result<Self, QuorumError>

Majority-quorum convenience: W = ceil((N+1)/2). Matches the ADR’s default.

Errors

Returns QuorumError::InvalidPolicy if n == 0.
