Error types for epoch operations.

Variants

Expired

Epoch has expired.

Fields

epoch: EpochId

The expired epoch.

BudgetExhausted

Epoch operation budget exhausted.

Fields

epoch: EpochId

The epoch that exceeded its budget.

budget: u32

The configured operation budget.

used: u32

Operations used so far.

TransitionOccurred

Epoch transition occurred during operation.

Fields

from: EpochId

The epoch when the operation started.

to: EpochId

The epoch when the operation ended.

Mismatch

Epoch mismatch.

Fields

expected: EpochId

The expected epoch.

actual: EpochId

The actual epoch.

ValidityViolation

Symbol validity window violation.

Fields

symbol_epoch: EpochId

The epoch of the symbol.

window: SymbolValidityWindow

The validity window.

BarrierTimeout

Barrier timeout.

Fields

epoch: EpochId

The epoch of the barrier.

arrived: u32

Number of participants arrived.

expected: u32

Number of expected participants.

Trait Implementations

impl Clone for EpochError

fn clone(&self) -> EpochError

Returns a duplicate 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)>

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<EpochError> for Error

fn from(e: EpochError) -> Self

Converts to this type from the input type.

impl PartialEq for EpochError

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

Tests for self and other values to be equal, and is used by ==.

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

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