Struct ProcessLeaseFence 

pub struct ProcessLeaseFence {
    pub predecessor: ProcessLease,
    pub successor: ProcessLease,
}

Durable proof that one exact stable-node process term was superseded after a full lease observation. The successor is the immediate create-only takeover record, not a wall-clock expiry estimate.

Fields

predecessor: ProcessLease

Last lease record owned by the process being fenced.

successor: ProcessLease

Immediate different-owner term that revoked the predecessor.

Implementations

impl ProcessLeaseFence

pub fn new( predecessor: ProcessLease, successor: ProcessLease, ) -> Result<Self, ProcessLeaseError>

Build an exact process-term transition.

Errors

Rejects different node namespaces, same-owner renewals, or a non-adjacent sequence/term.

pub fn is_canonical(&self) -> bool

Whether this is one exact create-only owner transition.
