Schema version identifier, monotonically increasing.

when: When

Time information for the lifecycle fact.

Location information for the lifecycle fact.

what: What

Typed event payload.

policy: Option<PolicyDecision>

Optional policy decision related to the event.

sequence: EventSequence

Monotonic event sequence.

correlation_id: CorrelationId

Correlation identifier shared by related signals.

config_version: u64

Configuration version that produced this fact.

scopes_triggered: Vec<MeltdownScope>

List of meltdown scopes that reached or exceeded thresholds in this evaluation round.

lead_scope: Option<MeltdownScope>

The dominant attribution scope for the effective meltdown verdict.

effective_protective_action: Option<ProtectionAction>

The effective protection action on the restrictiveness ladder.

cold_start_reason: ColdStartReason

Reason for cold start budget triggering or exhaustion.

hot_loop_reason: HotLoopReason

Reason for hot loop detection triggering.

throttle_gate_owner: ThrottleGateOwner

Ownership of the throttle gate that limited concurrent restarts.

Source that produced the effective policy.

Implementations

impl SupervisorEvent

pub fn new( when: When, where: Where, what: What, sequence: EventSequence, correlation_id: CorrelationId, config_version: u64, ) -> Self

Creates a supervisor lifecycle event.

Arguments

• when: Event timing.
• r#where: Event location.
• what: Event payload.
• sequence: Monotonic event sequence.
• correlation_id: Correlation identifier for related signals.
• config_version: Configuration version for this event.

Returns

Returns a SupervisorEvent.

Examples

let event = rust_supervisor::event::payload::SupervisorEvent::new(
    rust_supervisor::event::time::When::new(
        rust_supervisor::event::time::EventTime::deterministic(
            1,
            1,
            0,
            rust_supervisor::id::types::Generation::initial(),
            rust_supervisor::id::types::ChildStartCount::first(),
        ),
    ),
    rust_supervisor::event::payload::Where::new(
        rust_supervisor::id::types::SupervisorPath::root(),
    ),
    rust_supervisor::event::payload::What::ChildRunning { transition: None },
    rust_supervisor::event::time::EventSequence::new(1),
    rust_supervisor::event::time::CorrelationId::from_uuid(uuid::Uuid::nil()),
    1,
);
assert_eq!(event.what.name(), "ChildRunning");

pub fn with_policy(self, policy: PolicyDecision) -> Self

Attaches a policy decision to an event.

Arguments

• policy: Policy decision produced for this lifecycle fact.

Returns

Returns the updated SupervisorEvent.

Trait Implementations

impl Clone for SupervisorEvent

fn clone(&self) -> SupervisorEvent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SupervisorEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SupervisorEvent

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SupervisorEvent

fn eq(&self, other: &SupervisorEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SupervisorEvent

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SupervisorEvent
