Struct MetricGauge 

pub struct MetricGauge { /* private fields */ }

Current-value gauge (atomic i64).

Gauges go up and down — use them for values like “active leases” or “connections open”.

Examples

use grafos_observe::MetricGauge;

let g = MetricGauge::new();
g.inc();
g.inc();
g.dec();
assert_eq!(g.get(), 1);

g.set(-5);
assert_eq!(g.get(), -5);
