Struct InstalledReplayBaseline 

pub struct InstalledReplayBaseline { /* private fields */ }

The replay baseline a device stands on, as the history verifier needs it.

The snapshot owns its coverage and aggregate history state. Exact states at individual covered commits remain separate: the snapshot’s aggregate state cannot answer which devices were active at an earlier commit. Snapshot retention preserves those mappings while other commits still need them.

Without an installed snapshot, coverage is empty and history walks reach genesis.

Implementations

impl InstalledReplayBaseline

pub fn from_snapshot( snapshot: PublishedStoreSnapshot, covered_states: BTreeMap<StoreBatchCommitRef, Arc<ResolvedStoreDeviceState>>, ) -> Self

pub fn stands_on(&self, snapshot: &StoreSnapshotRef) -> bool

Whether this baseline was installed from snapshot itself.

pub fn snapshot(&self) -> Option<&PublishedStoreSnapshot>

The exact snapshot installed as this replay’s starting point.

pub fn coverage(&self) -> &CommitFrontier

pub fn covers(&self, reference: &StoreBatchCommitRef) -> bool

Whether the baseline restates reference, so no walk need pass it.

pub fn covered_state( &self, reference: &StoreBatchCommitRef, ) -> Option<&ResolvedStoreDeviceState>

The device state that stood at a covered position, or None when this device never recorded one there — which is a commit naming a position outside its own history, not a baseline that lost something.

pub fn covered_states( &self, ) -> impl Iterator<Item = (&StoreBatchCommitRef, &ResolvedStoreDeviceState)>
