Enum JobState 

pub enum JobState {
    Queued,
    Running,
    Done,
    Failed,
}

Where a job is. One enum for every kind, because all three status RPCs render the same four words and a per-kind copy of them was three chances to disagree about what Done means.

Variants

Queued

Waiting its turn.

Running

The one job of this kind that is running.

Done

Finished; the kind’s report is the answer.

Failed

Finished badly; error says why.

Implementations

impl JobState

pub fn is_live(self) -> bool

Whether a new request for the same subject should join this job rather than start another.

A queued or running job is the answer to “do this to this subject” — a second request wants the same outcome and has nothing to add. A finished one is not: the caller is asking for something that has not happened since, and refusing them because a job ran an hour ago would be the queue deciding it knows better.
