Struct UsageReporter 

pub struct UsageReporter { /* private fields */ }

Reporter that aggregates token usage and cost across the entire run.

UsageReporter listens for AgentEvent::UsageUpdated and AgentEvent::TurnFinished events and maintains a running UsageSummary. After the loop completes, call summary to read the totals.

Example

use agentkit_reporting::UsageReporter;
use agentkit_loop::LoopObserver;

let mut reporter = UsageReporter::new();

// ...pass `reporter` to the agent loop, then afterwards:
let summary = reporter.summary();
println!(
    "tokens: {} in / {} out",
    summary.totals.input_tokens,
    summary.totals.output_tokens,
);

Implementations

impl UsageReporter

pub fn new() -> Self

Creates a new UsageReporter with zeroed counters.

pub fn summary(&self) -> UsageSummary

Returns a snapshot of the current UsageSummary.

Trait Implementations

impl Default for UsageReporter

fn default() -> UsageReporter

Returns the “default value” for a type.

impl LoopObserver for UsageReporter

fn handle_event(&self, event: AgentEvent)

Called synchronously for every AgentEvent emitted by the loop driver. Observers store mutable state behind interior mutability (Mutex, atomics, channels) so the driver can share an Arc<dyn LoopObserver> across reusable Agent starts.
