LeaderLease

laminar_core::cluster::control::leader_lease

Struct LeaderLease 

Source 
pub struct LeaderLease {
    pub seq: u64,
    pub token: u64,
    pub owner: NodeId,
    pub expires_at_ms: i64,
}
Expand description

A durable leader lease record.

Fields§

§seq: u64

CAS sequence; bumps on every write.

§token: u64

Fencing token; bumps only when ownership changes.

§owner: NodeId

Current lease holder.

§expires_at_ms: i64

Expiry, millis since epoch. The lease is dead once now >= this.

Implementations§

Source§
