Relational build or snapshot export failures.

Variants

Plan(PlanError)

Snapshot planning failed.

Graph(GraphBuildError<u32, u32>)

CSR construction failed.

MissingSnapshotBytes

Engine build was invoked without snapshot bytes.

EmptyEdges

Build received no edge rows.

NodeCountOverflow

Distinct node count does not fit in u32 metadata.

EdgeCountOverflow

Edge count does not fit in u32 metadata.

EdgeCountMismatch

Forward and inbound edge counts diverged after transpose.

MissingNodeKey

An edge row referenced a node key that was not assigned.

MissingCsrSection

Required CSR section was absent during snapshot assembly.

Fields

kind: u32

Section kind that was expected.

MissingMetadataSection

Postgres metadata section was missing at engine open.

MalformedMetadata(String)

Section payload could not be interpreted.

MissingReverseIndex

Artifact metadata lacks the inbound CSC flag.

TopologyNodeCountMismatch

Forward and inbound node counts disagree at engine open.

TopologyEdgeCountMismatch

Forward and inbound edge counts disagree at engine open.

MetadataNodeCountMismatch

Forward node count disagrees with metadata.

MetadataEdgeCountMismatch

Forward edge count disagrees with metadata.

Spi(String)

SPI or extension boundary failure.

Trait Implementations

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<BuildError> for PostgresGraphError

fn from(error: BuildError) -> Self

Converts to this type from the input type.
