servo / heapsize
In support of measuring heap allocations in Rust programs.
servo/heapsize holds a health index of 18 out of 100, placing it in the Critical band. It scores highest on Sustainability & Governance (71/100) and lowest on Vitality (17/100). The repository is archived, so no further maintenance is expected.
18
overall / 100Software health index
Metrics are grouped into weighted categories on one standardized 1–100 scale. Overall starts as their weighted mean; when public evidence triggers the High-Risk Jurisdiction Policy, the rating is adjusted and receives an At risk ceiling of 49. AI Readiness sits outside the overall score.
18
Excellent85-100Exemplary; meets essentially all checked criteria
Good70-84Healthy; minor gaps
Moderate50-69Acceptable with notable gaps; review recommended
At risk30-49Significant weaknesses; adoption warrants caution
Critical1-29Severe problems (abandoned, single-maintainer, no hygiene)
Score profile
Each axis is a category. The shape matters more than the average — a healthy subject fills the whole shape, while a spike-and-crater profile means strength in one dimension is masking risk in another.
Abandonment Policy applies a 40% multiplier to weighted overall health and gives it a ceiling of 29.

Abandonment alert
Work has arrived and nobody has attended to it
archived on GitHub by its maintainersOverall rating: Critical ceiling
Silence alone is never the finding — a small, finished library may need no commits for years. This alert requires both: no human commit for a long time, and obligations the project is visibly not discharging. Automated commits do not count as maintenance.

When each star and fork was added, collected from GitHub and bucketed by day. Cumulative growth sits directly above the daily additions it is made of, so the two read against each other: steady organic accretion looks nothing like an abrupt, short-lived burst. Where that difference is measurable, it is reported as growth authenticity.

All dependencies 4
Full resolved dependency set from the GitHub dependency graph: 3 direct and 1 indirect (transitive) packages. The transitive closure is complete when the repository commits a lockfile.

| crates.io | winapi | — | indirect |
Dependency advisories 0
Installing crates:heapsize@0.4.2 pulls in 3 packages, direct and transitive: 0 carry known advisories, of which 0 are direct dependencies.
No known advisories affect the assessed dependencies.
An advisory means the version recorded in the dependency graph falls inside an advisory’s affected range. Reachability is not analysed, and the graph includes development and test pins — a finding may concern tooling rather than shipped software.

}Scores are signals, not warranties. They reflect publicly visible practices on GitHub — not a code audit, and not a security guarantee.
Missing data is excluded and weights renormalized, never scored as zero. Methodology is versioned and open: metrics v1.13.0, schema v0.27.0 — full methodology · metrics wiki.
