A histogram that uses free-running atomic counters to track the distribution
of values. They are only useful for recording values and producing
[crate::Snapshot]s of the histogram state which can then be used for
reporting.
A bucket represents a quantized range of values and a count of observations
that fall into that range.
The configuration of a histogram which determines the bucketing strategy and
therefore the relative error and memory utilization of a histogram.
A histogram that uses plain 64bit counters for each bucket.
A histogram that uses free-running non-atomic counters to track the
distribution of values. They are only useful for bulk recording of values
and producing [crate::Snapshot]s of the histogram state which can then be
used for reporting.
