Struct CompiledAbTest 

pub struct CompiledAbTest {
    pub name: String,
    pub variants: Vec<CompiledAbVariant>,
}

A compiled A/B test (DW-086): two or more variants with resolved targets. At request time, a deterministic weighted pick by request id selects a variant. Built at AiRuntime compile time from the config block; immutable once built.

Fields

name: String

The experiment name (for analytics/metrics attribution).

variants: Vec<CompiledAbVariant>

The compiled variants.

Implementations

impl CompiledAbTest

pub fn compile( name: &str, test: &AiAbTest, models: &BTreeMap<String, CompiledModel>, experiments: Option<&AiExperiments>, ) -> Option<Self>

Compile from config. Resolves each variant’s model alias to its primary RouteTarget against the first-pass compiled model map (plain chain/canary aliases only — an experiment alias cannot reference another experiment alias, so nested experiments are rejected by returning None). Returns None when a referenced alias is missing or is itself an experiment alias (a validate-vs-build race or an authoring error validation missed).

pub fn pick(&self, pick_key: &str) -> &CompiledAbVariant

The deterministic weighted pick for pick_key (the request id): the variant whose cumulative weight bound first exceeds pick_hash(key) % total. Same slot semantics as canary splits.
