Struct MembershipCore 

pub struct MembershipCore<P> { /* private fields */ }

The pure membership compute core: the SWIM state machine over a keyed peer map, driven by heartbeats and a logical clock. Emits PeerChangeEvents.

Implementations

impl<P: Ord + Clone> MembershipCore<P>

pub fn new(config: MembershipConfig) -> Self

pub fn alive_set(&self) -> BTreeSet<P>

The current alive peer set (the reactive PeerSet).

pub fn state(&self, peer: &P) -> Option<PeerState>

The state of a known peer.

pub fn join(&mut self, peer: P, now: u64) -> Vec<PeerChangeEvent<P>>

Join a peer (or refresh a re-joining one): Alive with a fresh detector.

pub fn heartbeat(&mut self, peer: P, now: u64) -> Vec<PeerChangeEvent<P>>

Record a heartbeat. An unknown peer is a join; a Suspect/Dead peer returns to Alive (SWIM refutation).

pub fn leave(&mut self, peer: P, _now: u64) -> Vec<PeerChangeEvent<P>>

Graceful departure.

pub fn tick(&mut self, now: u64) -> Vec<PeerChangeEvent<P>>

Advance the clock: escalate Alive → Suspect (phi crossed) and Suspect → Dead (timeout elapsed).
