Struct Metrics 

pub struct Metrics { /* private fields */ }

Process-lifetime metrics registry. Shared via Arc; lives in StaticState so it survives config reloads (like the rate-limit store).

Implementations

impl Metrics

pub fn new() -> Self

pub fn record(&self, outcome: Outcome, elapsed: Duration)

Record one finished request: its decision + total handling latency. Pure side effect.

pub fn render(&self) -> String

Serialize the current snapshot in Prometheus text exposition format. This is the Prometheus-specific exporter; the counters above are exporter-neutral.

Trait Implementations

impl Default for Metrics

fn default() -> Self

Returns the “default value” for a type.
