Variants

ThresholdError

Fields

stake_sum: Balance

num_seats: u64

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

EpochOutOfBounds(EpochId)

Tuple Fields

0: EpochId

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

MissingBlock(CryptoHash)

Tuple Fields

0: CryptoHash

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

IOErr(String)

Tuple Fields

0: String

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

NotAValidator(AccountId, EpochId)

Tuple Fields

0: AccountId

1: EpochId

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

ShardingError(String)

Tuple Fields

0: String

Error getting information for a shard

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

    Balance: BorshSerialize,
    u64: BorshSerialize,
    EpochId: BorshSerialize,
    CryptoHash: BorshSerialize,
    String: BorshSerialize,
    AccountId: BorshSerialize,
    EpochId: BorshSerialize,
    String: BorshSerialize, 

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8, Global>, Error>

Serialize this instance into a vector of bytes.

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 backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<EpochError> for RuntimeError

fn from(e: EpochError) -> Self

Performs the conversion.

impl From<Error> for EpochError

fn from(error: Error) -> Self

Performs the conversion.

impl PartialEq<EpochError> 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: &EpochError) -> bool

This method tests for !=.
