public static final class Distribution.Builder extends com.google.protobuf.GeneratedMessageV3.Builder<Distribution.Builder> implements DistributionOrBuilder
 `Distribution` contains summary statistics for a population of values. It
 optionally contains a histogram representing the distribution of those values
 across a set of buckets.
 The summary statistics are the count, mean, sum of the squared deviation from
 the mean, the minimum, and the maximum of the set of population of values.
 The histogram is based on a sequence of buckets and gives a count of values
 that fall into each bucket. The boundaries of the buckets are given either
 explicitly or by formulas for buckets of fixed or exponentially increasing
 widths.
 Although it is not forbidden, it is generally a bad idea to include
 non-finite values (infinities or NaNs) in the population of values, as this
 will render the `mean` and `sum_of_squared_deviation` fields meaningless.
