Implementations§

Source§

impl<B: HistogramBucketLabel> Histogram<B>

Source

pub(super) fn observe(&self, duration: Duration)

records one cumulative Prometheus histogram observation

every bucket at or above the selected bound is incremented so snapshots can be rendered directly as _bucket{le=...} samples

pub(super) fn load_bucket(&self, bucket: B) -> u64

Source

pub(super) fn load_count(&self) -> u64

Source

pub(super) fn load_sum_micros(&self) -> u64
