Enum FaultStateError 

#[non_exhaustive]
pub enum FaultStateError {
    CapacityExhausted {
        max: u32,
    },
    StaleReservation,
    Corrupt(FaultStateFormatError),
    Unbound,
    Unavailable,
}

A value-redacted fault-state reservation failure.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CapacityExhausted

The step already retains its maximum unresolved retry keys.

Fields

max: u32

The configured unresolved-key capacity.

StaleReservation

The supplied ordinal did not follow the persisted one.

A stale or concurrent writer loses rather than spending the same ordinal twice.

Corrupt(FaultStateFormatError)

Durable fault state could not be interpreted and no work may begin.

Unbound

A durable store was used before the runtime bound its step execution.

Unavailable

The fault state could not be read or written.

Trait Implementations

impl Clone for FaultStateError

fn clone(&self) -> FaultStateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FaultStateError

impl Debug for FaultStateError

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

Formats the value using the given formatter.

impl Eq for FaultStateError

impl Error for FaultStateError

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<FaultStateFormatError> for FaultStateError

fn from(error: FaultStateFormatError) -> Self

Converts to this type from the input type.

impl PartialEq for FaultStateError

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

Equality operator ==.

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

Inequality operator !=.
