Struct CostTracker 

pub struct CostTracker { /* private fields */ }

Tracks API costs across model invocations.

Implementations

impl CostTracker

pub fn new() -> Self

Create a new cost tracker with default model pricing.

pub fn estimate_cost( &self, model_name: &str, input_tokens: u64, output_tokens: u64, ) -> f64

Estimate the cost for a given model and token count.

pub fn record( &self, model_role: ModelRole, model_name: &str, input_tokens: u64, output_tokens: u64, )

Record an actual cost event.

pub fn total_cost(&self) -> f64

Get total cost across all recorded events.

pub fn cost_by_role(&self) -> HashMap<ModelRole, f64>

Get cost breakdown by model role.

pub fn events(&self) -> Vec<CostEvent>

Get all recorded events.

pub fn reset(&self)

Reset the tracker (clear all events).
