Enum TaskLookup 

pub enum TaskLookup {
    Active(TaskRecord),
    History(TaskHistoryRecord),
    NotFound,
}

Unified lookup result for querying a task by its dedup inputs.

Returned by [TaskStore::task_lookup] and [Scheduler::task_lookup]. Tells the caller whether a task is currently active (pending, running, or paused) or has finished (completed or failed), without requiring them to manually compute the dedup key or query two tables.

Variants

Active(TaskRecord)

Task is in the active queue (pending, running, or paused).

History(TaskHistoryRecord)

Task has finished and is in the history table. Contains the most recent history entry for that key.

NotFound

No task with this key exists in either table.
