Struct DurableRecoveryPlan

pub struct DurableRecoveryPlan {
    pub machine: ProtocolMachine,

Expand description

Typed durable recovery state derived from one checkpoint plus WAL suffix.

Fields§

§machine: ProtocolMachine

Decoded machine state at the checkpoint boundary.

§metadata: DurableRecoveryMetadata

Typed summary metadata for the durable suffix.

§wal_suffix: Vec<AgreementWalEntry>

WAL entries strictly after the checkpoint tick.

§evidence_cache: EvidenceOutcomeCacheArtifact

Evidence cache snapshot available during recovery.

§decisions: Vec<DurableRecoveryDecision>

Per-operation recovery decisions derived from the suffix.

Implementations§

impl DurableRecoveryPlan

pub fn from_checkpoint( checkpoint_tick: u64, machine: ProtocolMachine, wal: &AgreementWalArtifact, evidence_cache: EvidenceOutcomeCacheArtifact, ) -> Result<Self, String>

Build a typed recovery plan from one checkpointed machine and durable suffix.

§Errors

Returns an error if the WAL suffix violates monotonic escalation ordering.
