Module cost_tracker 

Available on crate feature eval only.

Cost and latency tracking for evaluation runs.

This module provides CostTracker which extracts token usage from agent event streams and computes estimated dollar costs using configurable per-model pricing tables.

Example

use adk_eval::cost_tracker::{CostTracker, CostMetrics};

let tracker = CostTracker::new();

// Compute cost for a known model
let cost = tracker.compute_cost("gpt-4o", 1000, 500);
assert!(cost.is_some());

// Unknown models return None
let cost = tracker.compute_cost("unknown-model", 100, 50);
assert!(cost.is_none());
