Errors returned by the Postgres graph engine library.

Concrete variants only — no boxed or dynamic error types on the public surface.

Variants

Snapshot(SnapshotError)

Snapshot bytes failed container validation.

ForwardSnapshot(CsrSnapshotError<u32, u32>)

Forward CSR topology sections could not be opened.

InboundSnapshot(CscSnapshotError)

Inbound CSC topology sections could not be opened.

NotLoaded

No graph engine is loaded in this session.

Build(BuildError)

Relational build or export failed.

Catalog(CatalogError)

Catalog registration is inconsistent or incomplete.

Query(QueryError)

Query limits or inputs were invalid.

Sync(SyncError)

Sync replay rejected a row or batch.

Config(ConfigError)

Operational configuration was invalid.

AccessDenied

Access control policy denied an operation.

Fields

required: GraphRole

Role required for the operation.

actual: GraphRole

Role observed in the session.

Trait Implementations

impl Debug for PostgresGraphError

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

Formats the value using the given formatter.

impl Display for PostgresGraphError

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

Formats the value using the given formatter.

impl Error for PostgresGraphError

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.
