}Expand description
A snapshot of histogram state at a point in time
Fields§
§buckets: Vec<f64>Upper bounds for each bucket
counts: Vec<u64>Cumulative count for each bucket (index i = count of observations <= buckets[i])
total_count: u64Total number of observations
sum: f64Sum of all observed values
Implementations§
Source§impl HistogramSnapshot
impl HistogramSnapshot
Sourcepub fn percentile(&self, p: f64) -> Option<f64>
pub fn percentile(&self, p: f64) -> Option<f64>
Calculate an approximate percentile (0.0..=1.0) from bucket data.
Uses linear interpolation within the bucket that contains the target rank.
Returns None if no observations have been recorded.
