Struct VolatileState 

Source 
pub struct VolatileState<D: Lattice> {
    pub delta_buffers: HashMap<ReplicaId, PeerDeltaBuffer<D>>,
    pub peer_acks: HashMap<ReplicaId, SeqNo>,
}
Expand description

Volatile state for causal anti-entropy (lost on crash)

Fields§

§delta_buffers: HashMap<ReplicaId, PeerDeltaBuffer<D>>

Per-peer delta buffers: Dᵢ[j]

§peer_acks: HashMap<ReplicaId, SeqNo>

Per-peer acknowledgment tracking: Aᵢ[j] Stores the last sequence number we’ve received from each peer
