Unified error type for all exo-core operations.

Variants

InvalidTransition

A BCTS state transition was requested that violates the state machine rules.

Fields

from: String

to: String

InvalidSignature

A cryptographic signature failed verification.

Fields

reason: String

InvalidDid

A DID string did not conform to the required format.

Fields

value: String

ClockDrift

The HLC detected backward drift beyond acceptable tolerance.

Fields

physical_ms: u64

tolerance_ms: u64

ClockOverflow

The HLC cannot advance because the timestamp space is exhausted.

Fields

physical_ms: u64

logical: u32

ClockUnavailable

The HLC wall-clock source could not produce a trustworthy timestamp.

Fields

reason: String

HashMismatch

A hash did not match the expected value.

Fields

expected: String

actual: String

Unauthorized

The actor does not have authority for the requested operation.

Fields

reason: String

ConsentRequired

An operation requires consent that has not been granted.

Fields

scope: String

InvariantViolation

A system invariant was violated.

Fields

description: String

SybilDetected

Sybil-resistant identity verification failed.

Fields

evidence: String

SerializationError

Serialization / deserialization failure.

Fields

reason: String

CryptoError

Cryptographic key generation or usage error.

Fields

reason: String

InvalidMerkleProof

Merkle proof verification failed.

ReceiptChainBroken

Receipt chain integrity check failed.

Fields

index: usize

NotFound

Entity not found.

Fields

entity: String

Implementations

impl ExoError

pub fn is_security_relevant(&self) -> bool

Returns true when this error indicates a security-relevant failure.

Trait Implementations

impl Clone for ExoError

fn clone(&self) -> ExoError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExoError

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

Formats the value using the given formatter.

impl Display for ExoError

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

Formats the value using the given formatter.

impl Eq for ExoError

impl Error for ExoError

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.

impl<T> From<Error<T>> for ExoError

fn from(e: Error<T>) -> Self

Converts to this type from the input type.

impl<T> From<Error<T>> for ExoError

fn from(e: Error<T>) -> Self

Converts to this type from the input type.

impl PartialEq for ExoError

fn eq(&self, other: &ExoError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
