Struct FaultPolicy 

pub struct FaultPolicy { /* private fields */ }

The validated retry, backoff, skip, and rollback policy for one step.

The runnable example lives in the oxide-batch facade documentation, because the supported import path is oxide_batch.

Implementations

impl FaultPolicy

pub fn new( classifier: FaultClassifier, retry_limit: RetryLimit, retry_state_limit: RetryStateLimit, skip_limit: SkipLimit, backoff: BackoffPolicy, ) -> Result<FaultPolicy, FaultPolicyError>

Validates and constructs the step policy.

Errors

Rejects a retry rule that no retry limit can ever satisfy, so a statically impossible combination cannot reach the runtime.

pub const fn classifier(&self) -> &FaultClassifier

Borrows the classifier.

pub const fn retry_limit(&self) -> RetryLimit

Returns the configured retry limit.

pub const fn retry_state_limit(&self) -> RetryStateLimit

Returns the unresolved retry-key capacity for one step.

pub const fn skip_limit(&self) -> SkipLimit

Returns the aggregate skip limit.

pub const fn backoff(&self) -> BackoffPolicy

Returns the backoff schedule.

pub fn requires_commit_safe_skip(&self) -> bool

Returns whether any rule accepts a commit-safe skip.

pub fn validate_capabilities( &self, supports_atomic_skip: bool, ) -> Result<(), FaultPolicyError>

Verifies the selected resource can honour the policy before user work.

Errors

Returns FaultPolicyError::CommitSafeSkipUnsupported when a rule accepts a commit-safe skip that the transaction capability cannot commit atomically.

pub fn decide( &self, fault: &FaultDescriptor, evidence: FaultEvidence, ) -> FaultDecision

Returns the authoritative decision for one fault.

The decision is a pure function of the policy, the framework-owned descriptor, and framework evidence, so it is reproducible after a restart.
