Crate oxgraph_csc 

Borrowed compressed-sparse-column (inbound) graph views.

Incoming adjacency is stored in Postgres-owned OXGTOPO sections (0x0201 / 0x0202). The physical layout matches CSR on transposed edges; this crate is separate from oxgraph_csr so forward and inbound views cannot be mixed at the type level.

Performance

Opening a snapshot-backed view is O(s + n + m) once per engine load.

Structs

CscNodeId

Dense node id in an inbound CSC view.

CscPredecessors

Iterator over predecessor node ids in one inbound row.

CscSnapshotGraph

Borrowed inbound adjacency (transpose-CSR / CSC layout).

Enums

CscSnapshotError

Errors while opening inbound CSC sections from a snapshot.

Constants

SNAPSHOT_KIND_PG_INBOUND_OFFSETS_U32

Postgres-owned inbound offsets section (0x0201).

SNAPSHOT_KIND_PG_INBOUND_TARGETS_U32

Postgres-owned inbound targets section (0x0202).

Type Aliases

CscInnerGraph

Snapshot-backed inbound CSC view for u32 node and edge indices.
