AckVector

nodedb_array::sync::ack

Struct AckVector 

Source 
pub struct AckVector { /* private fields */ }
Expand description

Per-replica ack watermark table.

Records grow monotonically — AckVector::record never moves a watermark backward. AckVector::min_ack_hlc returns None when no peers are known (cannot safely GC without knowing all peers have caught up).

Implementations§

Source§

impl AckVector

Source

pub fn new() -> Self

Create an empty AckVector.

Source

pub fn record(&mut self, replica: ReplicaId, hlc: Hlc)

Record that replica has applied all ops up to and including hlc.

Monotonic: if the existing watermark for replica is already higher, the call is a silent no-op.

Source

pub fn ack_for(&self, replica: ReplicaId) -> Option<Hlc>

Return the ack watermark for a specific replica, if known.

Source

pub fn min_ack_hlc(&self) -> Option<Hlc>

Return the minimum ack HLC across all tracked replicas.

Returns None if no replicas are tracked (GC must not proceed without knowing every peer’s progress).

Source

pub fn replicas(&self) -> impl Iterator<Item = ReplicaId> + '_

Iterate over all replica IDs currently tracked.
