Struct Process Lease Store &nbsp; Copy item path

impl ProcessLeaseStore

pub fn new(store: Arc<dyn ObjectStore>, node: NodeId, ttl_ms: i64) -> Self

Create an authority for node.

pub async fn load(&self) -> Result<Option<ProcessLease>, ProcessLeaseError>

Load the highest durable sequence.

§Errors

Fails on object-store I/O, malformed JSON, or a record in the wrong node namespace.

pub async fn try_acquire( &self, owner: Uuid, now_ms: i64, ) -> Result<ProcessLeaseOutcome, ProcessLeaseError>

Acquire or renew this stable node identity for owner at now_ms.

§Errors

Fails closed on object-store I/O or an invalid durable record.

pub fn observe_rival( &self, lease: &ProcessLease, ) -> Result<ProcessLeaseObservation, ProcessLeaseError>

Start a candidate-local monotonic observation of a rival lease.

§Errors

Rejects a malformed record or one from another node namespace.

pub async fn try_takeover( &self, owner: Uuid, observation: &ProcessLeaseObservation, now_ms: i64, ) -> Result<ProcessLeaseOutcome, ProcessLeaseError>

Attempt takeover after the same sequence and owner have been observed unchanged for a full TTL on this candidate’s monotonic clock.

§Errors

Fails closed on early observation, object-store I/O, or malformed durable state.
