Enum JoinError 

pub enum JoinError {
    Stale,
    SelfJoin,
    AlreadyJoined,
    Faulted,
}

Errors from super::TaskHandle::join.

Variants

Stale

The task slot was recycled since this handle was created (stale generation — ABA detection, plan.md §5.1).

SelfJoin

A task cannot join itself.

AlreadyJoined

Another task is already joined to this one (one joiner per task).

Faulted

The task was isolated by the fault policy before exiting (plan.md §3.4); it produced no result.
