A commit breaks a validation rule, or its group state cannot be read.

Variants

IdentitySequenceNotBeforeEnvelope

Identity updates must precede the group envelope. Not retryable.

Fields

identity_sequence: u64

Identity update sequence N named by the proposed membership.

envelope_sequence: u64

Authenticated group envelope sequence S; valid references have N < S.

ActorCouldNotBeFound

InboxValidationFailed(String)

InsufficientPermissions

InvalidVersionFormat(String)

ProtocolVersionTooLow(String)

ActorNotMember

SubjectDoesNotExist

MultipleActors

MissingGroupMembership

MissingMutableMetadata

UnexpectedInstallationAdded(Vec<Vec<u8>>)

SequenceIdDecreased

UnexpectedInstallationsRemoved(Vec<Vec<u8>>)

GroupMetadata(GroupMetadataError)

MlsCredential(BasicCredentialError)

GroupMutableMetadata(GroupMutableMetadataError)

ProtoDecode(DecodeError)

GroupMutablePermissions(GroupMutablePermissionsError)

NoPSKSupport

InvalidAppDataUpdateList(ComponentId)

The commit’s AppDataUpdate proposals conflict for this component under draft-ietf-mls-extensions-08 §4.7.

UnsupportedProposalType(ProposalType)

TooManyCharacters

Fields

length: usize

ProposerNotFound

ProposalsNotEnabled

MinVersionDowngrade

Sender published an AppDataUpdate(Update) against MIN_SUPPORTED_PROTOCOL_VERSION whose new value is below the existing floor. Monotonic-only: a downgrade silently unpauses peers between the new and old floors, defeating XIP §3’s gate.

Fields

requested: String

current: String

MinVersionRemoveOnExistingFloor

Sender published an AppDataUpdate(Remove) against MIN_SUPPORTED_PROTOCOL_VERSION on a group that already has a floor set. Explicit unsetting is just a downgrade in disguise, rejected for the same XIP §3 reason.

Fields

current: String

ComponentSource(ComponentSourceError)

A well-known component value in the AppData dictionary failed to decode while validating an AppDataUpdate proposal — most commonly a malformed COMPONENT_REGISTRY. Treated as a terminal wire-format violation so the offending commit is rejected rather than silently downgraded to “empty registry” (which would let a permissive validator state slip in).

Implementations

impl CommitRuleError

pub fn is_safe_rejection(&self) -> bool

Only authenticated, deterministic invalid input can advance the prefix. Unsupported versions and proposal types leave the head pending.

Trait Implementations

impl Debug for CommitRuleError

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

Formats the value using the given formatter.

impl Display for CommitRuleError

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

Formats the value using the given formatter.

impl Error for CommitRuleError

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.
