Histogram is a stats library for rust which provides histogram storage with percentile stats. It maintains precision guarentees throughout the range of stored values. The bucketing algorithm makes use of logarithmic outer buckets with linear steps between those buckets. This allows for storing a wide range of values - like latency in nanoseconds from one nanosecond all that way to minutes while maintaining precision of those recorded values.
