    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.
