Stable, value-redacted component-state validation failure.

No variant carries payload data: every field is a scalar identity or bound, mirroring StateError’s own redaction discipline.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyCodecId

A codec identifier was empty.

CodecIdTooLong

A codec identifier exceeded its UTF-8 byte limit.

Fields

max_bytes: usize

Maximum accepted UTF-8 bytes.

ZeroCodecVersion

A codec version was zero.

NonIncreasingCodecUpgrade

A declared codec-version upgrade did not strictly increase the version.

TooLarge

A serialized value exceeded its configured byte limit.

Fields

max_bytes: usize

Configured maximum bytes.

TooDeep

A serialized value exceeded its configured JSON depth.

Fields

max_depth: usize

Configured maximum depth.

Malformed

The bytes were not a valid envelope payload.

SchemaMismatch

The envelope schema does not match the selected codec.

UnsupportedSchemaVersion

Durable data was produced by a newer application schema.

Fields

found: u32

Version observed in durable data.

current: u32

Current version supported by the selected codec.

NoSchemaUpgradePath

The codec declares no directed schema upgrade reaching its current version.

Fields

found: u32

Version the chain stalled at.

current: u32

Current version supported by the selected codec.

AmbiguousSchemaUpgrade

Two declared schema upgrades leave the same version.

Fields

from: u32

Version left by more than one declared upgrade.

SchemaUpgradeOvershootsCurrent

A declared schema upgrade produces a version past the codec’s current version.

Fields

to: u32

Version the rejected edge produces.

current: u32

Current version supported by the selected codec.

SchemaUpgradeChainTooLong

The resolved schema-upgrade chain exceeded its bound.

Fields

max_upgrades: usize

Most upgrades one decode may apply.

UnknownCodec

The envelope’s codec identity does not match the selected codec.

UnsupportedCodecVersion

Durable data was produced by a newer codec version.

Fields

found: u32

Version observed in durable data.

current: u32

Current version supported by the selected codec.

ExternalSchemaMigrationUnsupported

An older external payload cannot be migrated without resolving its out-of-band bytes.

Fields

found: u32

Version recorded in the external envelope.

current: u32

Current version supported by the selected codec.

ExternalCodecMigrationUnsupported

An older external payload cannot be migrated without resolving its out-of-band bytes.

Fields

found: u32

Version recorded in the external envelope.

current: u32

Current version supported by the selected codec.

NoCodecUpgradePath

The codec declares no directed codec-version upgrade reaching its current version.

Fields

found: u32

Version the chain stalled at.

current: u32

Current version supported by the selected codec.

AmbiguousCodecUpgrade

Two declared codec-version upgrades leave the same version.

Fields

from: u32

Version left by more than one declared upgrade.

CodecUpgradeOvershootsCurrent

A declared codec-version upgrade produces a version past the codec’s current version.

Fields

to: u32

Version the rejected edge produces.

current: u32

Current version supported by the selected codec.

CodecUpgradeChainTooLong

The resolved codec-upgrade chain exceeded its bound.

Fields

max_upgrades: usize

Most upgrades one decode may apply.

ChecksumAlgorithmUnsupported

The declared checksum algorithm identity/version is not supported.

Fields

algorithm: u16

Algorithm identifier observed in durable data.

version: u16

Algorithm version observed in durable data.

ChecksumMismatch

The computed checksum does not match the recorded checksum.

No decode and no migration were attempted.

ExternalReferenceMissing

The payload is an external reference that has not been resolved.

ExternalReferenceContentMismatch

Resolved external content did not match its declared content identity.

InvalidPayload

The application payload was not valid JSON.

PayloadNotObject

The application payload was valid JSON but not an object.

Codec(StateCodecError)

The application codec rejected the payload without exposing its value.
