Class NoOpMetrics

java.lang.Object
io.github.teceli.resiliencia.metrics.NoOpMetrics
All Implemented Interfaces:
ResilienceMetrics
public final class NoOpMetrics extends Object implements ResilienceMetrics
A no-op ResilienceMetrics implementation that discards all recordings. Used by default when no backend is configured, to avoid null-checking or forcing consumers to provide a metrics implementation they may not need.

Thread-safe and lock-free. Suitable for use as a default or when metrics are deliberately disabled.
