Struct ErrorRateCounter 

pub struct ErrorRateCounter { /* private fields */ }

Error rate counter, based on a sliding time window for error rate statistics.

Samples outside the window are evicted on the next record call, ensuring rate() is always computed from the latest samples within the window.
