MembershipEvent

Events emitted by Room describing changes to member membership and liveness.

All events that carry timestamps use kotlin.time.Instant sourced from the injected clock — never kotlin.time.Clock.System.now() directly.

Types

The joiner's admit handshake failed terminally — it never entered a roster (joiner perspective only).

The host's transport link was permanently lost (joiner perspective only).

data class Joined(val member: Member) : MembershipEvent

A new peer completed the admit handshake and entered the roster.

data class Left(val peerId: PeerId, val reason: LeaveReason) : MembershipEvent

A peer left the room (clean leave or transport disconnect after admission).

This peer's own end of the fabric carrying this room can no longer carry frames.

This peer's own end of the room's fabric can carry frames again.

A peer's transport link dropped; a reconnect window may be open.

data class Recovered(val peerId: PeerId, val at: Instant) : MembershipEvent

A partitioned peer's link recovered before the window expired.

A partitioned joiner successfully resumed via Room.resume.

data class WindowOpened(val peerId: PeerId, val expiresAt: Instant) : MembershipEvent

A reconnect window opened for a peer whose link dropped.
