Struct Configuration 

pub struct Configuration { /* private fields */ }

Three ordered, distinct voters with an immutable confirmation policy.

Implementations

impl Configuration

pub fn new( group_id: GroupId, configuration_epoch: u64, digest: Digest, voters: [NodeId; 3], ) -> Result<Self, ReplicationError>

Validate an explicitly bootstrapped fixed configuration at view zero.

digest must identify the full durable configuration, including its authenticated voter mapping and ozzy_journal::integrity::PROFILE. Prefer ConfigurationRecord for that canonical binding. The digest is not computed from socket identities.

pub const fn policy(self) -> QuorumPolicy

Confirmation boundary bound into the canonical configuration digest.

pub const fn append_policy(self) -> Policy

Native writer policy bound to this immutable group configuration.

pub const fn scope(self) -> Scope

Initial configuration scope. Later views require the view-change protocol.

pub const fn voters(&self) -> &[NodeId; 3]

Ordered persistent voter identities.

pub fn primary(&self, view: u64) -> NodeId

Deterministic primary selection. Does not grant leadership authority.
