RunOutcome

Enum RunOutcome 

Source
pub enum RunOutcome {
    Completed(CompletedRecord),
    Skipped(SkipRecord),
    Cancelled(CancelledRecord),
}
Expand description

Terminal state of one task in a crate::run_graph invocation.

Completed wraps a CompletedRecord for any task that the scheduler admitted into the lookup-then-spawn pipeline and that reached a run classification (EXEC-009); Skipped wraps a SkipRecord for any task the cascade marked do-not-schedule before admission (EXEC-010 / EXEC-011); Cancelled wraps a CancelledRecord for any task that the cancellation flow (EXEC-012..015) reached, either directly (signalled in flight, drained from the ready set) or via cascade.

run_task itself returns the bare CompletedRecord (never wrapped in this enum) because a single-task lifecycle has no cascade to inspect.

Variants§

§

Completed(CompletedRecord)

A task that ran to a CompletedRecord (succeeded or failed per EXEC-009).

§

Skipped(SkipRecord)

A task the scheduler cascade-skipped before admission.

§

Cancelled(CancelledRecord)

A task the cancellation flow caught at any point (in flight, on the ready set, or via cascade).
