Variants

ThresholdError

Fields

pledge_sum: Balance

num_seats: u64

Error calculating threshold from given pledges for given number of seats. Only should happened if calling code doesn’t check for integer value of pledge > number of seats.

EpochOutOfBounds(EpochId)

Requesting validators for an epoch that wasn’t computed yet.

MissingBlock(CryptoHash)

Missing block hash in the storage (means there is some structural issue).

IOErr(String)

Error due to IO (DB read/write, serialization, etc.).

NotAValidator(AccountId, EpochId)

Given account ID is not a validator in the given epoch ID.

ShardingError(String)

Error getting information for a shard

NotEnoughValidators

Fields

num_validators: u64

num_shards: u64

ChunkValidatorSelectionError(String)

Error selecting validators for a chunk.

Trait Implementations

impl Clone for EpochError

fn clone(&self) -> EpochError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EpochError

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

Formats the value using the given formatter.

impl Display for EpochError

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

Formats the value using the given formatter.

impl Error for EpochError

fn source(&self) -> Option<&(dyn Error + 'static)>

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<BlockError> for EpochError

fn from(error: BlockError) -> Self

Converts to this type from the input type.

impl From<EpochError> for BlockError

fn from(error: EpochError) -> Self

Converts to this type from the input type.

impl From<EpochError> for RuntimeError

fn from(e: EpochError) -> Self

Converts to this type from the input type.

impl From<Error> for EpochError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl PartialEq for EpochError

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

This method tests for self and other values to be equal, and is used by ==.

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

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