Struct ActiveHealth 

pub struct ActiveHealth {
    pub kind: ProbeKind,
    pub path: String,
    pub interval_ms: u64,
    pub timeout_ms: u64,
    pub success_threshold: u32,
    pub failure_threshold: u32,
    pub jitter_ms: u64,
}

Active health check knobs (DW-013). A block with no keys enables HTTP probes with the defaults.

Probe semantics (frozen):

• http probes issue GET {path} over HTTP/1.1 DIRECTLY to the endpoint (bypassing load balancing and the pooled client); success is a 2xx status. Redirects (3xx) are NOT followed — a health endpoint answering 3xx is treated as a failure (a load balancer must not chase redirects to decide health).
• tcp probes succeed when a TCP connection completes within timeout_ms.
• Full jitter: each loop sleeps interval_ms plus a uniform random 0..jitter_ms before the next probe.

Fields

kind: ProbeKind

Probe kind (default http).

path: String

Path probed by http checks (default /healthz). Ignored by tcp.

interval_ms: u64

Time between probe attempts in milliseconds (default 5000). Must be

= timeout_ms and >= jitter_ms.

timeout_ms: u64

Per-probe timeout in milliseconds (default 2000), covering connect plus the response for http probes.

success_threshold: u32

Consecutive probe SUCCESSES required to (re)admit an ejected endpoint (default 2).

failure_threshold: u32

Consecutive probe FAILURES required to eject a healthy endpoint (default 3). Reports the same per-endpoint streak the passive checker uses; see the active-health module docs for precedence.

jitter_ms: u64

Full-jitter bound in milliseconds (default 500): each loop sleeps a uniform random 0..jitter_ms in addition to interval_ms. Must be <= interval_ms.

Trait Implementations

impl Clone for ActiveHealth

fn clone(&self) -> ActiveHealth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActiveHealth

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

Formats the value using the given formatter.

impl Default for ActiveHealth

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ActiveHealth

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for ActiveHealth

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.

impl PartialEq for ActiveHealth

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
