Struct CostCalculatorAdapter 

pub struct CostCalculatorAdapter { /* private fields */ }

Adapter that bridges any CostCalculator (ChatModel pricing source) into the EmbeddingCostCalculator surface.

Embeddings only consume input tokens, so the adapter constructs a synthetic Usage with input_tokens populated from the embedder’s EmbeddingUsage and delegates to the wrapped calculator. Operators with a single shared entelix_policy::CostMeter pricing table use this to charge embedding calls from the same source as model and tool calls — one pricing source, three cost surfaces, no drift.

Implementations

impl CostCalculatorAdapter

pub const fn new(inner: Arc<dyn CostCalculator>) -> Self

Wrap the supplied calculator. The adapter forwards every embed call as a synthetic Usage and lets the inner calculator’s pricing table do the lookup.

Trait Implementations

impl EmbeddingCostCalculator for CostCalculatorAdapter

fn compute_cost<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, model: &'life1 str, usage: &'life2 EmbeddingUsage, ctx: &'life3 ExecutionContext, ) -> Pin<Box<dyn Future<Output = Option<f64>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Compute the cost of one embedder call given the request context, the embedder model name (operator-supplied at MeteredEmbedder construction), and the embedder’s reported usage record.
