Struct ProxyMetrics 

pub struct ProxyMetrics {
    pub requests_total: AtomicU64,
    pub successes: AtomicU64,
    pub failures: AtomicU64,
    pub total_latency_ms: AtomicU64,
}

Per-proxy runtime metrics using lock-free atomic counters.

Intended to be shared via Arc<ProxyMetrics>.

Example

use stygian_proxy::types::ProxyMetrics;
let m = ProxyMetrics::default();
assert_eq!(m.success_rate(), 0.0);
assert_eq!(m.avg_latency_ms(), 0.0);

Fields

requests_total: AtomicU64

successes: AtomicU64

failures: AtomicU64

total_latency_ms: AtomicU64

Implementations

impl ProxyMetrics

pub fn success_rate(&self) -> f64

Returns the fraction of requests that succeeded, in [0.0, 1.0].

Returns 0.0 when no requests have been recorded.

Example

use stygian_proxy::types::ProxyMetrics;
use std::sync::atomic::Ordering;
let m = ProxyMetrics::default();
m.requests_total.store(10, Ordering::Relaxed);
m.successes.store(8, Ordering::Relaxed);
assert!((m.success_rate() - 0.8).abs() < f64::EPSILON);

pub fn avg_latency_ms(&self) -> f64

Returns the average request latency in milliseconds.

Returns 0.0 when no requests have been recorded.

Example

use stygian_proxy::types::ProxyMetrics;
use std::sync::atomic::Ordering;
let m = ProxyMetrics::default();
m.requests_total.store(4, Ordering::Relaxed);
m.total_latency_ms.store(400, Ordering::Relaxed);
assert!((m.avg_latency_ms() - 100.0).abs() < f64::EPSILON);

Trait Implementations

impl Debug for ProxyMetrics

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

Formats the value using the given formatter.

impl Default for ProxyMetrics

fn default() -> ProxyMetrics

Returns the “default value” for a type.
