Errors that can occur during consensus operations

Variants

InvalidProposal(String)

Invalid block proposal

InvalidVote(String)

Invalid vote

InsufficientVotes

Insufficient votes for quorum

Fields

got: u64

need: u64

NonValidator(String)

Vote from non-validator

DuplicateBlock(BlockHeight)

Block already exists

BlockNotFound(BlockHeight)

Block not found

InvalidHeight

Invalid block height

Fields

expected: BlockHeight

actual: BlockHeight

InvalidHash

Invalid block hash

Fields

expected: String

actual: String

InvalidSignature(String)

Invalid signature

ViewTimeout(u64)

View timeout

NotLeader(u64)

Not the leader for current view

AlreadyVoted(u64)

Already voted in this view

InvalidValidatorSet(String)

Invalid validator set

EpochTransition(String)

Epoch transition error

Mempool(String)

Mempool error

InvalidAttestation(String)

Invalid TEE attestation

Configuration(String)

Configuration error

Crypto(String)

Cryptographic error

Internal(String)

Internal error

NotStarted

Not started

AlreadyStarted

Already started

Equivocation

Equivocation detected

Fields

validator: String

view: u64

RateLimited

Per-DID admission lane bucket exhausted (Spec 2).

lane carries the lane the controller was assigned to; retry_after_ms is the controller’s best-effort hint for when one bucket token will be available; current_rate is the lane’s per-second refill in tokens/sec.

Fields

lane: &'static str

retry_after_ms: u64

burst_remaining: u32

current_rate: f64

FeeFloorTooLow

Per-DID admission lane fee-floor not met (Spec 2).

The lane multiplier is applied to the mempool’s static minimum gas price (mempool_min_gas_price) at admission time. Verified-lane controllers pay 1.0×, Delegated 1.5×, Open 4.0×. This makes unverified controllers strictly more expensive per-tx so they can’t trivially crowd out verified traffic during congestion.

Fields

lane: &'static str

gas_price: u64

required: u64

base: u64

multiplier: f64

Trait Implementations

impl Debug for ConsensusError

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

Formats the value using the given formatter.

impl Display for ConsensusError

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

Formats the value using the given formatter.

impl Error for ConsensusError

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<BlsError> for ConsensusError

fn from(err: BlsError) -> Self

Converts to this type from the input type.

impl From<CryptoError> for ConsensusError

fn from(err: CryptoError) -> Self

Converts to this type from the input type.
