Funnel counters across the whole run: how many fragments, candidate pairs and verified pairs each stage saw.

Fields

files: usize

Files analysed.

units: usize

Units across all files.

candidate: CandidateStats

Exact-seed candidate extraction statistics.

near_match: NearMatchStats

Near-match extraction statistics.

control_flow: ControlFlowStats

Control-flow skeleton extraction statistics.

maximal: RegionStats

Maximal-region consolidation statistics.

regions: usize

Duplicated runs confirmed against the source tokens.

region_singletons: usize

Occurrences dropped for holding content no other occurrence of their candidate run shared: the statement summaries agreed but the code did not.

region_overlapping: usize

Occurrences dropped for covering source a kept occurrence of the same run already covers, which makes them one stretch of code rather than two instances of it.

region_adjoining: usize

Occurrences dropped for continuing a kept occurrence of the same run, statement for statement, inside one block. Those tile one stretch of code, so the run is that stretch’s period rather than a copy of it.

region_subsumed: usize

Confirmed runs dropped because a longer run covers every one of their occurrences and claims at least as much about them.

region_merged: usize

Longer runs made by joining confirmed runs that describe one stretch at two offsets. The parts they cover leave through region_subsumed.

below_min_clone_token_regions: usize

Confirmed duplicated statement runs dropped because at least one occurrence is shorter than the configured minimum clone length.

nested_pairs: usize

Candidate pairs dropped because one unit encloses the other.

alternative_pairs: usize

Candidate pairs dropped because the two units sit under different arms of one preprocessor conditional, so no build holds both.

divergent_shape_pairs: usize

Candidate pairs dropped because the two units hold too different a mix of shapes for verification to have anything to find.

below_min_clone_token_pairs: usize

Candidate unit pairs dropped because one member is shorter than the configured minimum clone length.

unit_pairs: usize

Distinct unit pairs handed to verification.

verification_budget_dropped: usize

Candidate unit pairs left unverified after the verification budget was spent. A nonzero count means the reported groups can be incomplete.

verified_pairs: usize

Unit pairs that verification accepted as clones.

unrepresented_pairs: usize

Verified pairs no reported group holds both halves of.

described_pairs: usize

Verified pairs left out of that carry-out because a group already relates their two sides, one of them holding a unit nested inside the other side.

severed_pairs: usize

Verified pairs left out because the component ceiling cut their two sides into separate pieces, so no group was ever in a position to hold both. Zero unless GroupingConfig::max_component fired.

grouping: GroupingStats

Grouping statistics.

siblings: SiblingSweepStats

Post-grouping sibling-sweep accounting.
