Enum foca::Notification
source · [−]pub enum Notification<T> {
MemberUp(T),
MemberDown(T),
Active,
Idle,
Defunct,
Rejoin(T),
}Expand description
A Notification contains information about high-level relevant state changes in the cluster or Foca itself.
Variants
MemberUp(T)
Foca discovered a new active member with identity T.
MemberDown(T)
A previously active member has been declared down by the cluster.
If Foca detects a down member but didn’t know about its activity before, this notification will not be emitted.
Can only happen if MemberUp(T) happened before.
Active
Foca’s current identity is known by at least one active member of the cluster.
Fired when successfully joining a cluster for the first time and every time after a successful identity change.
Idle
All known active members have either left the cluster or been declared down.
Defunct
Foca’s current identity has been declared down.
Manual intervention via Foca::change_identity or
Foca::reuse_down_identity is required to return to a functioning
state.
Rejoin(T)
Foca automatically changed its identity and rejoined the cluster after being declared down.
This happens instead of Defunct when identities opt-in on
Identity::renew() functionality.
