pub enum SubscriptionUpdate {
Matched(MatchedCheckpoint),
WatermarkTick {
checkpoint: u64,
tx_hi: u64,
},
}Expand description
Updates delivered to a subscriber while processing checkpoints. An initial progress frame may precede a matched frame for the entry checkpoint.
Variants§
Matched(MatchedCheckpoint)
WatermarkTick
An initial tick identifies the safe position immediately before
subscription entry: checkpoint is the entry checkpoint minus one and
tx_hi is the entry checkpoint’s transaction lower bound. A periodic
tick identifies a fully processed checkpoint; tx_hi is its
network_total_transactions (the exclusive transaction upper bound).
