pub fn mutated_lines(report: &MutantsReport) -> MutatedLinesExpand description
The (file, line) locations cargo-mutants produced a viable, conclusive mutant
for — caught or missed (CaughtMutant / MissedMutant), not the inconclusive
Timeout / Unviable. The #226 line-scoped guard reads this to tell an
over-exemption (a listed line whose mutants were all caught, no survivor) from an
out-of-scope line (no mutant there at all — e.g. outside a --base diff).
