Struct MetricDetailTransition 

pub struct MetricDetailTransition {
    pub previous_effective: i32,
    pub effective: i32,
    pub transition_kind: String,
    pub client_id: Option<String>,
}

Worker-emitted cardinality-lease transition. Populates the Event.metric_detail field when a worker’s effective level changes because a lease was applied, renewed, expired (TTL janitor), or cleared. The master folds these into the audit log alongside the operator-initiated transitions emitted from bin/src/command/requests.rs::worker_request, closing the gap where worker-local expiries previously left no audit trail.

Fields

previous_effective: i32

The worker’s effective cardinality level BEFORE the transition.

effective: i32

The worker’s effective cardinality level AFTER the transition.

transition_kind: String

What caused the transition. Stable strings: “lease_tick_expired” (janitor retired one or more leases), “lease_apply” (worker arm applied a lease), “lease_clear” (worker arm cleared a lease). Operator-initiated apply/clear emit master-side; the worker still emits this Event so the SubscribeEvents bus has one canonical signal for cardinality changes regardless of origin.

client_id: Option<String>

Operator-supplied lease key (SetMetricDetail.client_id) when the transition was triggered by an explicit apply/clear. Empty for janitor expiries, which clear many leases at once.

Implementations

impl MetricDetailTransition

Sets previous_effective to the provided enum value.

pub fn effective(&self) -> MetricDetail

Returns the enum value of effective, or the default if the field is set to an invalid enum value.

pub fn set_effective(&mut self, value: MetricDetail)

Sets effective to the provided enum value.

pub fn client_id(&self) -> &str

Returns the value of client_id, or the default value if client_id is unset.
