Struct Meter 

pub struct Meter { /* private fields */ }

A compound stat that includes a rate metric and a cumulative total metric.

Implementations

impl Meter

pub fn new(rate_metric_name: MetricName, total_metric_name: MetricName) -> Self

Construct a Meter with seconds as time unit, backed by a WindowedSum.

pub fn with_unit( unit: TimeUnit, rate_metric_name: MetricName, total_metric_name: MetricName, ) -> Self

Construct a Meter with the provided time unit, backed by a WindowedSum.

pub fn with_rate_stat( rate_stat: Arc<SampledStat>, rate_metric_name: MetricName, total_metric_name: MetricName, ) -> Self

Construct a Meter with seconds as time unit and a provided rate stat.

pub fn with_unit_rate_stat( unit: TimeUnit, rate_stat: Arc<SampledStat>, rate_metric_name: MetricName, total_metric_name: MetricName, ) -> Self

Construct a Meter with the provided time unit and rate stat.

Panics if rate_stat is not a WindowedSum/WindowedCount, mirroring Java’s IllegalArgumentException — this is a construction-time programming error (Meter is only meaningful with a windowed sum/count).

Trait Implementations
