Detailed Description

A type that supports gauge metric operations.

Types supporting gauge operations.

Types satisfying this concept can set gauge metrics, which represent instantaneous values that can go up or down.

Example usage:

template<GaugeMetric M>
void report_memory(M& collector, double bytes) {
    collector.gauge("memory_usage_bytes", bytes);
}
