Struct RateCard 

pub struct RateCard { /* private fields */ }

Published prices, keyed by model identifier.

Deliberately not bundled with Layover. Prices change, they differ per provider and per context tier, and a stale table baked into a release is exactly how a cost estimate drifts by a factor of two without anyone noticing. Whoever runs the factory owns this.

Implementations

impl RateCard

pub fn new() -> Self

Creates an empty rate card.

pub fn with(self, model: impl Into<String>, rates: ModelRates) -> Self

Adds rates for a model.

pub fn rates_for(&self, model: &str) -> Option<&ModelRates>

Returns the rates for model, if any are published.

pub fn is_empty(&self) -> bool

Returns true when no rates are published at all.

pub fn estimate(&self, model: &str, usage: TokenUsage) -> Option<f64>

Estimates what usage cost on model.

Returns None when the model is unknown or its rates are unusable, which the caller must treat as CostSource::Unreported rather than as zero.

pub fn price( &self, run: RunId, itinerary: ItineraryId, agent: AgentName, model: Option<String>, usage: TokenUsage, ) -> RunCost

Builds a RunCost for a run that reported tokens but no dollars.

Falls back to CostSource::Unreported — not to a zero that would flatter the totals — when there is no model, no published rate, or no usage to price.
