Struct OutlierDetection 

pub struct OutlierDetection {
    pub consecutive_gateway_failures: u32,
    pub base_ejection_time_ms: u64,
    pub max_ejection_percent: u32,
}

Per-upstream outlier-detection policy (ADR 000032). A THIRD resilience axis: active health (ADR 000017) asks “is the instance reachable?”, the circuit breaker (ADR 000028) “is the upstream saturated?”, and this “is the instance misbehaving on live traffic?”. An ejected instance leaves the rotation for a (backing-off) ejection window, independent of the health bit; a shed request (circuit breaker) never feeds it, only real upstream 5xx responses do.

Fields

consecutive_gateway_failures: u32

Consecutive gateway-class 5xx (502/503/504) from live forwards to eject an instance; 0 = disabled (the default). Counts only real responses — a circuit-breaker 503 or a per-try timeout is not an instance-misbehaviour signal.

base_ejection_time_ms: u64

Base ejection duration (ms): an ejected instance is out of rotation this long, doubling per consecutive ejection up to a bounded cap, then auto-returns when the window expires (no probe needed). Default 30000.

max_ejection_percent: u32

Max % of the pool that may be outlier-ejected at once. The rest stay in rotation even while failing — fail-closed must not become a self-inflicted total outage (ejecting every instance). Default 10.

Trait Implementations

impl Clone for OutlierDetection

fn clone(&self) -> OutlierDetection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OutlierDetection

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

Formats the value using the given formatter.

impl Default for OutlierDetection

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OutlierDetection

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for OutlierDetection

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.
