Struct LeaderHandover 

pub struct LeaderHandover { /* private fields */ }

Watcher that detects leader transitions across successive MembershipState snapshots. Stateful: holds the previous snapshot’s leader and emits a LeaderHandoverEvent only on change.

Wire it up by calling LeaderHandover::observe every gossip tick — a Some(event) return value means a handover occurred and should be published. Across-process handover comes from the cluster daemon broadcasting these events on the crate::ClusterEventBus via remote.
