Struct ApiMetrics 

pub struct ApiMetrics { /* private fields */ }

Live, aggregate request metrics for the embedding API service.

These counters are updated by request handlers (via ApiMetrics::record) and read back by the health/info endpoints. They replace the previously hard-coded placeholder values so that reported latency/error figures reflect real observed traffic. Before any request is recorded the derived rates are 0.0, which is their true value rather than a fabricated constant.

Implementations

impl ApiMetrics

pub fn new() -> Self

Create an empty metrics tracker.

pub fn record(&self, latency: Duration, is_error: bool)

Record a completed request with its wall-clock latency and outcome.

pub fn total_requests(&self) -> u64

Total number of recorded requests.

pub fn avg_response_time_ms(&self) -> f64

Mean response time in milliseconds over all recorded requests (0.0 if none).

pub fn error_rate_percent(&self) -> f64

Error rate as a percentage over all recorded requests (0.0 if none).

Trait Implementations

impl Debug for ApiMetrics

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

Formats the value using the given formatter.

impl Default for ApiMetrics

fn default() -> ApiMetrics

Returns the “default value” for a type.
