Enum AiRoutingPolicy 

pub enum AiRoutingPolicy {
    FallbackChain(AiFallbackChainPolicy),
    LatencyCost(AiLatencyCostPolicy),
}

A routing policy (DW-085 ai.routing_policies.<name>): within-request escalation or latency-vs-cost selection. Keyed by name in ai.routing_policies. An alias declares routing_policy: <name> to be served by one; the policy is evaluated per request and composes over DW-076 routing (the candidate aliases it names are themselves plain chain/canary aliases). Internally tagged by kind so the YAML shape is:

routing_policies:
  my-policy:
    kind: fallback_chain
    cheap: cheap-model
    escalate_to: expensive-model
    classifier_url: http://...
    classifier_model: complexity

Variants

FallbackChain(AiFallbackChainPolicy)

Cheap-model-first with complexity-signal escalation (DW-085). Calls an external classifier service to estimate prompt complexity; simple prompts (score < threshold) use the cheap model, complex prompts (score >= threshold) escalate to the costlier model. On classifier error, fails open to the cheap model (the safe default).

LatencyCost(AiLatencyCostPolicy)

Latency-vs-cost routing (DW-085): static config-based selection. The operator declares cost/latency scores per candidate and a preference; the policy picks deterministically at compile time (no runtime metrics needed).

Trait Implementations

impl Clone for AiRoutingPolicy

fn clone(&self) -> AiRoutingPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AiRoutingPolicy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AiRoutingPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for AiRoutingPolicy

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 AiRoutingPolicy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
