A fast and modular metrics library decoupling app instrumentation from reporting backend. Similar to popular logging frameworks, but with counters and timers. Can be configured for combined outputs (log + statsd), random sampling, local aggregation of metrics, recurrent background publication, etc.
```rust // Send any metrics values directly to the "appmetrics" logger let mut appmetrics = DirectDispatch::new(LogSink::new("app_metrics"));
// define a timer named "timerb" let timer = appmetrics.newtimer("timerb");
// record time spent in computevalue() using closure or macro syntax let value1 = timer.time(||, computevalue1()); let value2 = time!(timer, compute_value2()); ```
