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.

Arguments

• rate_metric_name - the name of the rate metric
• total_metric_name - the name of the cumulative total metric

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.

Arguments

• unit - the time unit of the rate
• rate_metric_name - the name of the rate metric
• total_metric_name - the name of the cumulative total metric

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.

Arguments

• rate_stat - the sampled stat of the rate, a WindowedSum or WindowedCount
• rate_metric_name - the name of the rate metric
• total_metric_name - the name of the cumulative total metric

Panics

If rate_stat is not a WindowedSum or WindowedCount.

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 provided time unit.

Arguments

• unit - the time unit of the rate
• rate_stat - the sampled stat of the rate, a WindowedSum or WindowedCount
• rate_metric_name - the name of the rate metric
• total_metric_name - the name of the cumulative total metric

Panics

If rate_stat is not a WindowedSum or WindowedCount, with the message of Java’s IllegalArgumentException: a construction-time programming error.
