Struct CircuitBreaker 

pub struct CircuitBreaker {
    pub max_requests: u32,
}

Per-upstream circuit-breaker thresholds (ADR 000028). Overload protection that is deliberately SEPARATE from outlier detection / health (ADR 000017): health answers “is this instance up?”, the breaker answers “is this upstream saturated?”. A request rejected by the breaker is the upstream shedding load, not an instance failing — so it never demotes an instance.

Fields

max_requests: u32

Max concurrent in-flight requests the fast path will forward to this upstream at once. At the cap a new request fails closed with 503 (x-plecto-fault: circuit-open) rather than piling onto the backend. 0 = unlimited (the default). Counts one slot per request across the whole retry sequence, released when the upstream response headers arrive (or it fails).

Trait Implementations

impl Clone for CircuitBreaker

fn clone(&self) -> CircuitBreaker

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CircuitBreaker

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

Formats the value using the given formatter.

impl Default for CircuitBreaker

fn default() -> CircuitBreaker

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CircuitBreaker

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for CircuitBreaker

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.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
