Errors raised by chain verification.

Variants

EmptyChain

Empty chain provided to verifier.

InvalidGenesis

Genesis event has non-null prev_event_hash.

Fields

event_id: String

Event id of the offending event.

PrevHashMismatch

prev_event_hash on event N does not match this_event_hash on event N-1.

Fields

event_id: String

Event id of the offending event.

expected: Option<String>

Expected prev_event_hash (i.e., previous event’s this_event_hash).

got: Option<String>

Actual prev_event_hash on this event.

HashMismatch

this_event_hash does not match recomputed value.

Fields

event_id: String

Event id of the offending event.

Serde(Error)

Serialization failure during canonicalization.

Trait Implementations

impl Debug for ChainError

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

Formats the value using the given formatter.

impl Display for ChainError

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

Formats the value using the given formatter.

impl Error for ChainError

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 From<ChainError> for SignatureError

fn from(source: ChainError) -> Self

Converts to this type from the input type.

impl From<Error> for ChainError

fn from(source: Error) -> Self

Converts to this type from the input type.
