Struct Metrics 

pub struct Metrics { /* private fields */ }

Thread-safe metrics handle for in-process telemetry.

Implementations

impl Metrics

pub fn is_enabled(&self) -> bool

Whether this metrics instance currently records values.

pub fn set_enabled(&self, enabled: bool)

Enable or disable metrics collection at runtime.

pub fn snapshot(&self) -> MetricsSnapshot

Return a point-in-time snapshot of current metrics values.

pub fn record_order_created(&self, _customer_id: &str, amount: f64)

Record a new order creation event.

pub fn record_customer_created(&self, _customer_id: &str)

Record a new customer creation event.

pub fn record_product_created(&self, _product_id: &str)

Record a new product creation event.

pub fn record_return_requested(&self, _return_id: &str)

Record a new return request event.

pub fn record_cart_created(&self, _cart_id: &str)

Record a new cart creation event.

pub fn record_cart_checkout_completed(&self, _cart_id: &str, _order_id: &str)

Record a completed cart checkout event.

pub fn record_shipment_created(&self, _shipment_id: &str)

Record a new shipment creation event.

pub fn record_shipment_delivered(&self, _shipment_id: &str)

Record a shipment delivery event.

pub fn record_subscription_created(&self, _subscription_id: &str)

Record a new subscription creation event.

pub fn record_payment_completed(&self, _payment_id: &str, amount: f64)

Record a completed payment.

pub fn record_inventory_adjusted(&self, _sku: &str, delta: f64)

Record an inventory adjustment.

pub fn record_a2a_quote_created(&self)

Record an A2A quote creation.

pub fn record_a2a_purchase_created(&self)

Record an A2A purchase creation.

pub fn record_x402_intent_created(&self)

Record an x402 payment intent creation.

pub fn record_x402_intent_settled(&self)

Record an x402 payment intent settlement.

pub fn record_policy_evaluation(&self, denied: bool)

Record a policy evaluation.

pub fn record_agent_registration(&self)

Record an agent registration.

pub fn record_webhook_delivery(&self, failed: bool)

Record a webhook delivery attempt.

pub fn record_pqc_signature(&self, profile: &str)

Record a PQC signature operation by security profile.

profile should be "legacy", "hybrid", or "pqc-strict".

pub fn record_pqc_encryption(&self, profile: &str)

Record a PQC encryption operation by security profile.

profile should be "legacy", "hybrid", or "pqc-strict".

pub fn record_request( &self, operation: &str, duration: Duration, is_error: bool, )

Record a request in RED metrics.

operation is normalized to a low-cardinality label.

pub fn record_http_request( &self, method: &str, route: &str, status: u16, duration: Duration, )

Record an HTTP request in per-route RED metrics.

route should be a low-cardinality route pattern (e.g. axum’s MatchedPath such as /api/v1/orders/{id}), never a raw request path. 4xx and 5xx responses are counted separately; only 5xx responses are treated as errors for the global RED aggregate.

pub fn record_request_success(&self, operation: &str, duration: Duration)

Record a successful request in RED metrics.

pub fn record_request_error(&self, operation: &str, duration: Duration)

Record a failed request in RED metrics.

Performs copy-assignment from source.

impl Debug for Metrics

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>
