Errors arising from Core Protocol handshake operations.

Variants

UnsupportedVersion

The protocol version in the received message is not supported.

Fields

received: u8

The version received from the peer.

supported: u8

The version this implementation supports.

InvalidChallenge

A challenge failed the Section 4 field constraints.

Fields

reason: String

What constraint failed.

InvalidProof

A proof failed the Section 15.3 shape checks.

Fields

reason: String

What constraint failed.

NonceMismatch

The nonce echoed in the proof does not match the challenge.

Fields

expected: String

The nonce in the challenge.

received: String

The nonce echoed in the proof.

ChallengeExpired

The challenge nonce has expired (anti-replay protection).

Fields

issued: String

When the challenge was issued.

expiry: String

When it expired.

now: String

Current timestamp.

ReplayDetected

A nonce was reused (replay attack detected).

Fields

nonce_hex: String

Hex-encoded nonce that was replayed.

SignatureVerificationFailed

Signature verification failed against the trusted key set.

Fields

reason: String

Why verification failed.

InvalidDidDocument

The peer’s DID document is structurally invalid or missing required fields.

Fields

did: String

The DID whose document was invalid.

reason: String

What was wrong.

TransportFailed

The transport layer failed to send or receive a message.

Fields

reason: String

Underlying transport error.

Timeout

A timeout occurred waiting for a response from the peer.

Fields

step: String

Which protocol step timed out.

timeout_secs: u64

How long we waited.

SerializationFailed

Serialization or deserialization of a protocol message failed.

Fields

message_type: String

The message type being (de)serialized.

reason: String

Underlying failure reason.

ExpiryTooLong

The challenge expiry duration exceeds the maximum allowed (300 seconds, per Section 7 of the Core Protocol Specification).

Fields

requested_secs: u64

The requested expiry in seconds.

max_secs: u64

The maximum allowed.

Internal(String)

An internal failure that is not the peer’s fault (e.g. a poisoned lock in a session store). Surfaced rather than panicked, per the workspace no-panic policy.

SessionNotFound

A presented session token does not identify a live session.

Fields

session_id: String

The token or identifier presented.

SessionExpired

A session exists but has expired and was removed.

Fields

session_id: String

The token or identifier presented.

Trait Implementations

impl Debug for AuthProtocolError

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

Formats the value using the given formatter.

impl Display for AuthProtocolError

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

Formats the value using the given formatter.

impl Error for AuthProtocolError

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.
