Classes

• RunComparator — Compares two benchmark runs and produces deltas, group summaries, and statistics.

Functions

• compare_runs — Compare two runs and calculate per-case deltas.

• summarize_groups — Build group-level summary from case-level deltas.

• build_overview_statistics — Compute accumulated comparison statistics.

• build_method_statistics — Compute statistics for one benchmark method.

• build_method_group_split_bars — Build split-bar chart rows per method base name for original/new roles.

source class RunComparator(reference_run: BenchmarkRun, candidate_run: BenchmarkRun)

Compares two benchmark runs and produces deltas, group summaries, and statistics.

Methods

• compare — Calculate per-case deltas between reference and candidate runs.

• build_split_bars — Build split-bar chart rows per method base name for original/new roles.

• summarize_groups — Build group-level summary from case-level deltas.

• build_overview_statistics — Compute accumulated comparison statistics.

• build_method_statistics — Compute statistics for one benchmark method.
