let counter = CounterBuilder::new("count") .defaultregistry() .finish() .unwrap(); let gauge = GaugeBuilder::new("gauge") .label("foo", "bar") .defaultregistry() .finish() .unwrap();

counter.increment(); gauge.set(12.3);

let metrics = defaultgatherer().lock().unwrap().gather(); asserteq!( metrics.to_text(), format!("{}\n{}\n{}\n{}\n", "# TYPE count counter", "count 1", "# TYPE gauge gauge", "gauge{foo=\"bar\"} 12.3")); ```
