Struct MergedChanges

What merge decides for the paths a barrier changes (lever G, latency plan §12): everything but the foreign set, which is about every OTHER path. merge is this over the whole document plus that set, so a path cannot be decided two ways.

Fields

seq: u64

The merged document’s generation.

overlay: BTreeMap<String, Option<LeanEntry>>

Each changed path’s entry in the merged document: Some cited (an upsert), None no longer cited (a delete that applied to a cited path). Every other path is theirs, as it stands.

tombstones: BTreeMap<String, Tombstone>

The merged document’s tombstones, whole.

overridden: Vec<(String, LeanEntry)>

deletes: BTreeMap<String, DeleteOutcome>

recreated: Vec<(String, String)>

over_theirs: Vec<(String, LeanEntry)>
