Struct ServiceSplit 

pub struct ServiceSplit {
    pub targets: Vec<SplitTarget>,
    pub canary_analysis: Option<CanaryAnalysis>,
}

Weighted traffic split across upstreams (DW-040, services[].split): canary releases and blue-green switches at the SERVICE level — each target is a full upstream (its own endpoints, protocol, health, and balancer), so a canary pool is isolated from the stable one by construction. The pick is a deterministic weighted hash (see Service::split): ratios hold statistically per request and exactly per session when sticky affinity is on.

Fields

targets: Vec<SplitTarget>

The weighted targets. Validation enforces 2..=8 entries (one target is what services[].upstream expresses), existing upstream names, no duplicates, and a positive total weight (a total of 0 would route nowhere; individual zeros are the parked side of a blue-green pair).

canary_analysis: Option<CanaryAnalysis>

Auto-canary analysis (DW-091): when set, a background controller compares the canary (second target) vs the baseline (first target) on error rate or latency and adjusts the split weights automatically. Only valid when the split has exactly 2 targets (baseline + canary). Weight changes are transient (Generation swap) and revert on config reload.

Trait Implementations

impl Clone for ServiceSplit

fn clone(&self) -> ServiceSplit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServiceSplit

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ServiceSplit

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for ServiceSplit

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 ServiceSplit

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
