ChangeScore returns an indicator of the change and direction.

NewBuilder creates a new Builder for collecting benchmark results into tables.

NormalizeDateString converts dates in two formats used in bent/benchmarking into UTC, so that all sort properly into a single order with no confusion.

ParseNormalizedDateString parses a time in the format returned by NormalizeDateString.

This is the interval-overlap heuristic.

This is a Kolmogorov-Smirnov statistic.

RFC3339NanoNoZ has the property that formatted date&time.000000000 < date&time.000000001, unlike RFC3339Nano where date&timeZ > date&timeZ.000000001Z i.e., "Z" > "." but "+" < "." so if ".000000000" is elided must use "+00:00" to express the Z time zone to get the sort right.

A Builder collects benchmark results into a set of tables, and transforms that into a slice of ComparisonSeries.

A Cell is the observations for part of a benchmark comparison.

A Comparison is a pair of numerator and denominator measurements, the date that they were collected (or the latest date if they were accumulated), an optional slice of medians of ratios of bootstrapped estimates and an optional summary node that contains the spreadsheet/json/database summary of this same information.

ComparisonHashes contains the git hashes of the two tool chains being compared.

A ComparisonSeries describes a table/graph, indexed by paired elements of Benchmarks, Series.

A ComparisonSummary is a summary of the comparison of a particular benchmark measurement for two different versions of the toolchain.

CrossGlyph is a glyph that draws a big X.

SeriesKey is a map key used to index a single cell in a ComparisonSeries.
