MetricsGuard

tiny_proxy::metrics

Struct MetricsGuard 

Source 
pub struct MetricsGuard { /* private fields */ }
Expand description

RAII guard that tracks one in-flight request.

On creation, increments the http_active_requests gauge. Call .record(status) to record the request counter + latency histogram. On drop, decrements the gauge.

Implementations§

Source§

impl MetricsGuard

Source

pub fn new(_method: String, _site: String) -> Self

Source

pub fn record(&mut self, status: u16)

Record the request counter + duration histogram for this request.
