Struct PeakEwmaConfig 

pub struct PeakEwmaConfig {
    pub decay_ms: Option<u64>,
    pub default_rtt_ms: Option<u64>,
}

Peak-EWMA load-balancing tuning (DW-090, upstreams[].peak_ewma). Only consulted when load_balancer: peak_ewma; ignored otherwise.

Fields

decay_ms: Option<u64>

Decay tau in milliseconds (default 10 000 = 10 s). The EWMA weight is exp(-td / tau) where td is the time since the last update. A larger tau makes the cost track slow endpoints more sluggishly (more stable, less reactive); a smaller tau reacts faster to latency changes. Must be > 0.

default_rtt_ms: Option<u64>

Initial cost in milliseconds (default 250). A fresh endpoint’s EWMA cost starts here (converted to nanoseconds) so the first picks have a reasonable baseline before any real RTT is observed. Must be > 0.

Trait Implementations

impl Clone for PeakEwmaConfig

fn clone(&self) -> PeakEwmaConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PeakEwmaConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PeakEwmaConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PeakEwmaConfig

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 PeakEwmaConfig

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
