Enum ResultClaim 

pub enum ResultClaim {
    Accept {
        task: Task,
        attempt: usize,
        attempts: usize,
        late: Option<LateResult>,
        replaced: Option<(usize, TaskStatus)>,
    },
    Superseded {
        attempt: usize,
        finished: usize,
    },
    Stale {
        attempt: usize,
    },
    Unknown,
}

What the sink may do with a result, decided by InFlightSet::claim_result.

Variants

Accept

Report it for task: it is the task’s newest finished attempt.

Fields

task: Task

the task the result is for

attempt: usize

the attempt it belongs to (0-based)

attempts: usize

how many attempts were dispatched

late: Option<LateResult>

Some when the result came after its lease expired

replaced: Option<(usize, TaskStatus)>

the earlier accepted result this one replaces (its attempt and status), if any — restored by InFlightSet::note_publish_failed if this one cannot be published

Superseded

Drop it: a result already accepted stands — a newer attempt’s, or a usable one that a newer attempt’s failure (Fatal/Invalid) must not replace.

Fields

attempt: usize

the attempt it belongs to

finished: usize

the attempt whose result stands

Stale

Drop it: it belongs to an earlier run of the task (an operator re-ran it since — D-28).

Fields

attempt: usize

the attempt it belongs to

Unknown

No such task in flight or in its late-result window: drop it.
