Enum UpdateStateError

pub enum UpdateStateError<V: Value> {
    PartyStatusMismatch(PartyStatusMismatch),
    BallotNumberMismatch(BallotNumberMismatch),
    LeaderMismatch(LeaderMismatch),
    ValueMismatch(ValueMismatch<V>),
    ValueVerificationFailed,
    DeserializationError(DeserializationError),
}

Represents the various errors that can occur when updating the state in a consensus protocol.

This enum is generic over V, which must implement the Value trait.

Variants

PartyStatusMismatch(PartyStatusMismatch)

Occurs when there is a mismatch in the expected party status.

• 0: The specific PartyStatusMismatch that caused the error.

BallotNumberMismatch(BallotNumberMismatch)

Occurs when there is a mismatch in the ballot number.

• 0: The specific BallotNumberMismatch that caused the error.

LeaderMismatch(LeaderMismatch)

Occurs when there is a mismatch in the expected leader.

• 0: The specific LeaderMismatch that caused the error.

ValueMismatch(ValueMismatch<V>)

Occurs when there is a mismatch in the expected value.

• 0: The specific ValueMismatch<V> that caused the error, where V is the type of the value.

ValueVerificationFailed

Occurs when the value verification fails during the state update process.

DeserializationError(DeserializationError)

Occurs when there is an error during deserialization.

• 0: The specific DeserializationError encountered.

Trait Implementations

impl<V: Debug + Value> Debug for UpdateStateError<V>

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

Formats the value using the given formatter.

impl<V: Value> Display for UpdateStateError<V>

where ValueMismatch<V>: Display,

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

Formats the value using the given formatter.

impl<V: Value> Error for UpdateStateError<V>

where Self: Debug + Display,

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<V: Value> From<BallotNumberMismatch> for UpdateStateError<V>

Converts a BallotNumberMismatch into an UpdateStateError<V>.

This conversion is used when there is a ballot number mismatch during state updates, allowing the error to be propagated and handled as an UpdateStateError.

fn from(error: BallotNumberMismatch) -> Self

Converts to this type from the input type.

impl<V: Value> From<DeserializationError> for UpdateStateError<V>

Converts a DeserializationError into an UpdateStateError<V>.

This conversion is used when a deserialization error occurs during state updates, allowing the error to be handled within the context of state updates.

fn from(error: DeserializationError) -> Self

Converts to this type from the input type.

impl<V: Value> From<LeaderMismatch> for UpdateStateError<V>

Converts a LeaderMismatch into an UpdateStateError<V>.

This conversion is used when there is a leader mismatch during state updates, allowing the error to be propagated and handled as an UpdateStateError.

fn from(error: LeaderMismatch) -> Self

Converts to this type from the input type.

impl<V: Value> From<PartyStatusMismatch> for UpdateStateError<V>

Converts a PartyStatusMismatch into an UpdateStateError<V>.

This conversion is useful when a status mismatch occurs while updating the state, allowing the error to be handled within the context of state updates.

fn from(error: PartyStatusMismatch) -> Self

Converts to this type from the input type.

impl<V: Value> From<ValueMismatch<V>> for UpdateStateError<V>

Converts a ValueMismatch<V> into an UpdateStateError<V>.

This conversion is used when there is a value mismatch during state updates, allowing the error to be propagated and handled as an UpdateStateError.

fn from(error: ValueMismatch<V>) -> Self

Converts to this type from the input type.
