Struct StepExecution 

pub struct StepExecution { /* private fields */ }

One attempt to execute a named step within a job execution.

Implementations

impl StepExecution

pub const fn new( id: StepExecutionId, job_execution_id: JobExecutionId, step_name: StepName, metadata: ExecutionMetadata, ) -> Self

Constructs a step execution record from validated metadata.

pub const fn from_snapshot( id: StepExecutionId, job_execution_id: JobExecutionId, step_name: StepName, metadata: ExecutionMetadata, version: ExecutionVersion, ) -> Self

Reconstructs a step execution snapshot with its optimistic version.

pub const fn id(&self) -> StepExecutionId

Returns the step-attempt identifier.

pub const fn job_execution_id(&self) -> JobExecutionId

Returns the enclosing job-execution identifier.

pub const fn step_name(&self) -> &StepName

Borrows the logical step name.

pub const fn metadata(&self) -> &ExecutionMetadata

Borrows the execution metadata.

pub const fn version(&self) -> ExecutionVersion

Returns the facade-owned optimistic-lock version.

pub fn transition( &mut self, expected_version: ExecutionVersion, transition: LifecycleTransition, ) -> Result<ExecutionVersion, LifecycleError>

Applies one legal lifecycle transition using compare-and-swap semantics.

Errors

Returns a typed lifecycle/conflict error without mutating this snapshot.

pub fn enrich_exit_status( &mut self, expected_version: ExecutionVersion, exit_status: ExitStatus, ) -> Result<ExecutionVersion, LifecycleError>

Enriches flow/operator exit status without changing batch status.

Errors

Returns a typed conflict/version error without mutating this snapshot.

pub fn new_restart_attempt( &self, expected_version: ExecutionVersion, new_execution_id: StepExecutionId, new_job_execution_id: JobExecutionId, created_at: SystemTime, ) -> Result<Self, LifecycleError>

Creates a fresh STARTING step attempt under a new job execution.

The prior step execution remains unchanged.

Errors

Returns a typed stale-version, non-restartable, or reused-ID error.
