Enum ValidationError

    Protobuf(DecodeError),

Variants

MissingPayload

The payload selection is absent. Not retryable.

MissingWelcomeVersion

The welcome version is absent. Not retryable.

Protobuf(DecodeError)

Protobuf framing is malformed. Not retryable.

Tls(Error)

MLS framing is malformed. Not retryable.

Protocol(ProtocolMessageError)

The MLS body is not a protocol message. Not retryable.

InvalidTopic(ConversionError)

The topic identifier has an invalid shape. Not retryable.

Inbox(FromHexError)

The inbox identifier is not hexadecimal. Not retryable.

KeyPackage(KeyPackageVerificationError)

The key package fails existing validation. Not retryable.

IdentityEncoding(ConversionError)

Identity fields cannot be decoded, for example a field is unset or unlisted, or an Ethereum identifier is not in its one form. Not retryable.

Association(AssociationError)

Identity state transition failed. Nested verifier failures can be retryable.

Signature(SignatureError)

Signature verification failed. Provider and I/O failures can be retryable.

StaleBlock(u64)

An ERC-6492 signature names a block after the chain head or more than MAX_BLOCK_AGE_SECS before it. Not retryable.

InvalidAccountId(ConversionError)

An ERC-6492 signature’s account id is not a CAIP-10 account id, so the signature cannot be verified. Not retryable.

Implementations

impl ValidationError

pub fn reason(&self) -> Reason

Classify this error for the backend publish response.

The transport supplies the input index. Retryability is kept separate so a provider failure can become UNAVAILABLE instead of a bad-payload reason. An identity update is malformed only when its inbox id names no topic; every other identity failure is a signature or identity reason.

Trait Implementations

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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

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

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