Struct CostTracker 

pub struct CostTracker { /* private fields */ }

Cost tracker — accumulates token usage and computed costs per agent.

Usage: call record(agent_id, model, usage) after each LLM call, then query snapshot(agent_id) or global_snapshot().

Implementations

impl CostTracker

pub fn new( model_registry: Arc<ModelRegistry>, config: CostTrackerConfig, ) -> CostTracker

Create a new cost tracker.

pub fn record(&self, agent_id: &str, model: &Model, usage: TokenUsage)

Record token usage for an agent using a model’s pricing.

pub fn snapshot(&self, agent_id: &str) -> Option<CostSnapshot>

Snapshot for a specific agent.

pub fn global_snapshot(&self) -> GlobalCostSnapshot

Global snapshot across all agents.

pub fn is_over_budget(&self, agent_id: &str) -> bool

Returns true if the agent has exceeded its per-agent budget.

pub fn is_over_global_budget(&self) -> bool

Returns true if the total across all agents exceeds the global budget.

pub fn agent_cost(&self, agent_id: &str) -> f64

Get current total cost for an agent.

pub fn reset(&self, agent_id: &str)

Reset counters for a specific agent.

pub fn reset_all(&self)

Reset all counters.
