Errors that can occur during witness operations.

These errors cover the full range of failure modes for async witness interactions, from network issues to security violations.

Variants

Network(String)

Network error communicating with witness.

Duplicity(DuplicityEvidence)

Duplicity detected - the controller presented different events.

This is a security violation indicating a potential split-view attack.

Rejected

The witness rejected the event.

This can happen if the event is malformed, the witness doesn’t track this identity, or the event fails validation.

Fields

reason: String

Human-readable reason for rejection

Timeout(u64)

Operation timed out.

InvalidSignature

Invalid receipt signature.

Fields

witness_id: String

The witness that provided the invalid signature

InsufficientReceipts

Insufficient receipts to meet threshold.

Fields

got: usize

Number of receipts received

required: usize

Number of receipts required

SaidMismatch

Receipt is for wrong event.

Fields

expected: Said

Expected event SAID

got: Said

Actual SAID in receipt

Storage(String)

Storage error.

Serialization(String)

Serialization error.

Trait Implementations

impl Debug for WitnessError

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

Formats the value using the given formatter.

impl Display for WitnessError

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

Formats the value using the given formatter.

impl Error for WitnessError

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.
