Enum CorrelationKey 

pub enum CorrelationKey {
    Activity(u64),
    Child(u64),
    Timer(TimerId),
    Signal {
        name: String,
        index: usize,
    },
}

Deterministic identity for one world-touching workflow call.

Variants

Activity(u64)

Activity scheduled at the deterministic ordinal carried by its aion_core::ActivityId.

Tuple Fields

0: u64

Deterministic scheduling ordinal.

Child(u64)

Child workflow scheduled at the deterministic spawn ordinal.

The ordinal is positional: the n-th spawn_child call a run makes correlates with the n-th recorded ChildWorkflowStarted in that run’s history segment. Like activity ordinals it restarts at zero for every run, so replay re-derives the same identity regardless of how many asynchronous-arrival events (signals, timer fires) interleave.

Tuple Fields

0: u64

Zero-based spawn ordinal within the run segment.

Timer(TimerId)

Timer selected by workflow code or assigned by the engine.

Tuple Fields

0: TimerId

Timer identifier from the recorded timer-start event.

Signal

Signal delivery by name and zero-based occurrence for that name in history order.

Fields

name: String

Signal name selected by workflow code.

index: usize

Zero-based occurrence of this signal name in recorded history order.
