Struct RepairProofs 

pub struct RepairProofs { /* private fields */ }

Evidence that this node has sent replica repair hints for local keys.

The map is keyed by record key so each key retains only one close-group snapshot and at most that snapshot’s peers. This bounds memory by local key count times the replication close-group size rather than by churn history.

Implementations

impl RepairProofs

pub fn new() -> Self

Create an empty repair-proof table.

pub fn record_replica_hint_sent( &mut self, peer: PeerId, key: XorName, current_close_peers: &HashSet<PeerId>, hinted_at_epoch: u64, ) -> bool

Record that peer was sent a replica repair hint for key.

current_close_peers must be the current self-inclusive close group for key. If that close group differs from the previous proof snapshot, proofs for peers that left the close group are invalidated before recording. Stable peers keep their proofs, while a peer that leaves and later re-enters still needs a fresh hint.

pub fn has_mature_replica_hint( &mut self, peer: &PeerId, key: &XorName, current_close_peers: &HashSet<PeerId>, current_epoch: u64, ) -> bool

Whether this node has mature repair-hint evidence for (peer, key).

The check invalidates proofs for peers that have left the current self-inclusive close group. A proof is mature only after at least one later local sync-cycle epoch.

pub fn remove_key(&mut self, key: &XorName)

Remove all repair proofs for a key, e.g. after local deletion.

pub fn remove_peer(&mut self, peer: &PeerId)

Remove all repair proofs for a peer, e.g. after routing-table removal.
