Struct LatencyHistogram 

pub struct LatencyHistogram {
    pub buckets: Vec<u64>,
    pub counts: Vec<u64>,
    pub overflow: u64,
}

Histogram for latency distribution.

Fields

buckets: Vec<u64>

Bucket boundaries in microseconds.

counts: Vec<u64>

Counts for each bucket.

overflow: u64

Count of values above last bucket.
