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.

RetryLimitOutOfRange

A retry limit exceeded the bounded representation.

Fields

max: u32

The largest accepted limit.

RetryOrdinalOutOfRange

A retry ordinal exceeded the bounded representation.

Fields

max: u32

The largest accepted ordinal.

RetryStateLimitOutOfRange

The unresolved retry-key capacity was outside its bound.

Fields

min: u32

The smallest accepted capacity.

max: u32

The largest accepted capacity.

BackoffDelayTooLong

A backoff delay exceeded the accepted maximum.

Fields

max_seconds: u64

The largest accepted delay in seconds.

ZeroBackoffMultiplier

An exponential schedule used a zero multiplier.

BackoffMaximumBelowInitial

An exponential ceiling was below its initial delay.

NotPolicyEligible

A rule addressed a phase or category that fails closed in M3.

Fields

phase: FaultPhase

The rejected phase.

category: FailureCategory

The rejected category.

PhaseNotSkippable

A rule accepted a skip for a phase that cannot commit one.

Fields

phase: FaultPhase

The rejected phase.

CommitSafeSkipPhase

A rule accepted a commit-safe skip after a possible external effect.

Fields

phase: FaultPhase

The rejected phase.

CommitSafeSkipUnsupported

The selected resource cannot commit a skip atomically.

DuplicateRule

Two rules addressed the same phase and category.

Fields

phase: FaultPhase

The repeated phase.

category: FailureCategory

The repeated category.

UnreachableRetryRule

A retry rule could never be satisfied by the configured retry limit.

Fields

phase: FaultPhase

The affected phase.

category: FailureCategory

The affected category.

SkipCountOverflow

Checked skip-count arithmetic rejected the update.

impl Eq for FaultPolicyError

impl Error for FaultPolicyError

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
