Typed graph traversal rejection.

Variants

Geometry(String)

Request shape or graph/rescore geometry is invalid.

Profile(GraphProfileError)

The pinned epoch has no measured automatic graph profile.

Graph(GraphNodeError)

A validated node became unavailable through the fixed-stride view.

Quant(QuantError)

Query preparation or Bit4 scoring rejected the input.

Gather(GatherShapeError)

The four-row gather boundary rejected a graph/query shape mismatch.

AdaptiveEf(AdaptiveEfError)

Adaptive or explicit ef resolution rejected the request.

Rescore(RescoreError)

The canonical f32 pool-rescore path rejected its inputs.

FilteredCandidateShortfall

A filtered traversal retained fewer allowed rows than the requested result count.

Fields

k: usize

Requested result count.

candidates: usize

Allowed candidates retained by the original traversal.

counters: GraphSearchCounters

Exact work performed by that original traversal before refusal.

ExactRescoreUnavailable(String)

Chunk-local integrity validation rejected exact-rescore bytes.

VisitedCapExceeded

Unfiltered traversal crossed the Task-16 collapse guard; M6 owns fallback.

Fields

visited: usize

Distinct nodes marked before traversal stopped.

cap: usize

Fail-closed guard 4 * ef * R.

Cancelled

The caller cancelled traversal; partial answers are never returned.

Fields

partial: bool

Permanently false.

Timeout

The query deadline expired; partial answers are never returned.

Fields

partial: bool

Permanently false.

ReadCancelled

Store close cancelled the admitted read; partial answers are never returned.

Fields

partial: bool

Permanently false.

Scan(ScanError)

An unexpected scan-layer cancellation check failed.

Trait Implementations

impl Clone for GraphSearchError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GraphSearchError

fn fmt(&self, f: &mut Formatter<'_>) -> Result
