Typed local journal identity, schema or transition rejection.

Variants

UnsupportedVersion(u16)

Only v1 records are maintained.

EmptyArtifacts

An empty physical set cannot claim completion.

TooManyArtifacts

The bounded artifact count was exceeded.

DuplicateCanister

More than one snapshot was selected for the same physical canister.

InvalidPrincipal

The supplied principal failed canonical admission.

InvalidSnapshotId

The exact snapshot token is empty, excessive or contains nongraphic bytes.

ArtifactPathMismatch

A persisted path differs from its immutable identity-derived location.

UnknownArtifact

The requested physical target is not retained.

SnapshotMismatch

The supplied snapshot differs from the retained exact token.

InvalidStateTransition

Progress cannot be reset, repeated or advanced over an intermediate state.

Fields

from: ArtifactStateRecord

Retained state.

to: ArtifactStateRecord

Rejected next state.

InvalidChecksumState(ArtifactStateRecord)

Checksum evidence disagrees with lifecycle state.

Checksum(ChecksumError)

The immutable intent or checksum is malformed.

Trait Implementations

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
