Enum RemoveEdgeOutcome 

pub enum RemoveEdgeOutcome {
    RemovedFromOverlay,
    TombstonedBase,
}

Outcome of Topology::remove_edge, distinguishing the two “not removed from overlay” cases that have different semantics for callers aware of a base CSR.

Variants

RemovedFromOverlay

Edge was present in the overlay and has been removed. edge_count was decremented.

TombstonedBase

Edge was NOT present in the overlay. A tombstone has been recorded in both out_tombstones and in_tombstones so TopologyView::neighbors will subtract it from the base CSR during reads and snapshot-merges. The edge may or may not exist in the base CSR — the tombstone is a no-op if it does not.
