Enum EventKind 

pub enum EventKind {
    BreakerOpened,
    BreakerHalfOpen,
    BreakerClosed,
    EndpointEjected,
    EndpointRecovered,
    ConfigPublished,
    ConfigRejected,
    QuotaNearLimit,
    CanaryPromoted,
    CanaryRolledBack,
    ProbeFailed,
    ProbeRecovered,
}

Every event kind the gateway emits (DW-044). Closed set: webhook events lists are validated against EventKind::from_config.

Variants

BreakerOpened

A per-upstream circuit breaker moved closed -> open. Payload: upstream, detail (the rule that tripped).

BreakerHalfOpen

An open breaker’s cooling-off elapsed: the next request becomes a half-open probe. Payload: upstream.

BreakerClosed

A half-open probe succeeded: the breaker closed again. Payload: upstream.

EndpointEjected

Passive or active health ejected an endpoint from rotation. Payload: upstream, endpoint.

EndpointRecovered

An ejected endpoint recovered (successful probe or fail-open success) and is back in rotation. Payload: upstream, endpoint.

ConfigPublished

A config generation was validated, compiled, and published. Payload: generation, content_hash, route_count.

ConfigRejected

A config candidate was rejected (validation or compile failure); the previously published generation keeps serving. Payload: issue_count, generation (the one still running).

QuotaNearLimit

A consumer’s request budget crossed the near-limit threshold (80% of the window’s cap; DW-033). Payload: consumer, detail (the budget: “daily” or “monthly”), used, limit. Edge-triggered once per (consumer, budget, window): the SECOND crossing inside one window is not re-emitted, and the counter resets with the window itself.

CanaryPromoted

A canary group was promoted (DW-091): the auto-canary controller increased the canary weight. Payload: canary_group, canary_action, canary_weight, canary_metric_value.

CanaryRolledBack

A canary group was rolled back (DW-091): the auto-canary controller decreased the canary weight (or rolled it to 0 on severe regression). Payload: canary_group, canary_action, canary_weight, canary_metric_value.

ProbeFailed

DP-10 (#238): a synthetic probe crossed the failure threshold and entered an alerting state. Edge-triggered: subsequent consecutive failures do not re-fire. Payload: route, status, latency_ms, detail.

ProbeRecovered

DP-10 (#238): a previously-alerting synthetic probe recovered (a successful probe after an alert). Payload: route, status, latency_ms.

Implementations

impl EventKind

pub const ALL: &'static [EventKind]

The closed set, in display order. The source of webhook events validation and of every doc list — keep the two in lockstep.

pub fn is_critical(self) -> bool

REL-14 (#249): whether this event kind is “critical” and should be persisted to the WAL before emission. Critical events are the ones an operator or controller needs for post-incident investigation and fleet-state reconstruction: breaker transitions, endpoint ejections/recoveries, config publish/reject, quota near-limit, and canary promotions/rollbacks. Probe events are excluded (high-volume, operational not critical).

pub fn as_str(self) -> &'static str

Stable wire/config spelling (serde’s snake_case form, spelled out so it can be used in labels and validation messages without serializing).

pub fn from_config(value: &str) -> Option<EventKind>

Parse one gateway.webhooks[].events[] entry. Unknown spellings are None (validation turns them into an issue naming the accepted set).

Trait Implementations

impl Clone for EventKind

fn clone(&self) -> EventKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EventKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for EventKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EventKind

fn eq(&self, other: &EventKind) -> 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 EventKind

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for EventKind
