Struct WeightedRouter 

pub struct WeightedRouter { /* private fields */ }

Weighted router: pick the child with the highest weight. On ties the earliest index wins (so all-equal weights behave like RuleRouter — always child 0). Missing trailing weights default to 0.0. NaN at index > 0 loses to any finite weight (NaN at index 0 wins only because nothing compares greater than NaN — avoid NaN weights). To route by cost (lowest-cost first), pass reciprocals or negative weights.

Implementations

impl WeightedRouter

pub fn new(weights: Vec<f64>) -> Self

Weights are positional — weights[i] applies to models[i]. Missing trailing weights default to 0.0.

Trait Implementations

impl Router for WeightedRouter

fn route( &self, _prompt: &LanguageModelPrompt, models: &[ChildModel], ) -> Result<usize, AiMuxError>

Choose a child-model index. Err means “no child can serve this prompt”.
