Struct LeaderLease 

pub struct LeaderLease {
    pub seq: u64,
    pub renewal_sequence: u64,
    pub token: u64,
    pub owner: LeaderLeaseOwner,
    pub expires_at_ms: i64,
    pub catalog_manifest: Option<CatalogManifestRef>,
}

Durable leader lease record.

Fields

seq: u64

Append-only compare-and-set sequence.

renewal_sequence: u64

Monotonic liveness sequence, advanced only by an acquisition or renewal.

token: u64

Fencing token, stable across uninterrupted renewals and advanced for each authority term.

owner: LeaderLeaseOwner

Exact process incarnation holding the lease.

expires_at_ms: i64

Owner-written wall-clock expiry for diagnostics only.

catalog_manifest: Option<CatalogManifestRef>

Immutable catalog content reference, once sealed for this control namespace.
