Structured validation failures for witness-graph CSR preparation.

Variants

InvalidOffsetCount

edge_offsets was not exactly node_count + 1 entries.

Fields

offsets: usize

Actual offset entries.

expected: usize

Required offset entries.

OffsetCountOverflow

node_count + 1 overflowed the host index type.

Fields

nodes: usize

Number of graph nodes.

EdgeArrayLengthMismatch

edge_targets and edge_kind_mask did not both match final offset.

Fields

targets: usize

Number of target entries.

kinds: usize

Number of edge-kind entries.

EdgeCountOverflow

A CSR edge count or edge offset could not be represented by the host index type while preparing the reverse witness graph.

Fields

edges: usize

Edge count or edge offset that overflowed host indexing.

NonZeroInitialOffset

CSR offsets did not start at zero.

Fields

first: u32

Supplied first offset.

NonMonotonicOffsets

CSR offsets decreased between adjacent rows.

Fields

source: usize

Source row whose start exceeded its end.

start: usize

Row start offset.

end: usize

Row end offset.

OffsetExceedsEdgeCount

A row end exceeded the final declared edge count.

Fields

offset_index: usize

Offset index that exceeded the edge count.

offset: usize

Offset value.

edges: usize

Declared edge count.

ReverseEdgeCountOverflow

Reverse CSR edge count overflowed while preparing predecessor rows.

Fields

node: usize

Destination node whose incoming edge count overflowed.

TerminalOffsetMismatch

Final CSR offset did not match the supplied edge arrays.

Fields

terminal: usize

Final offset value.

edges: usize

Supplied edge count.

TargetOutOfBounds

An edge target named a node outside the graph.

Fields

edge_index: usize

Edge index.

target: u32

Target node id.

node_count: u32

Valid node count.
