Compare with similar projects
Order: strongest tier first, then most downloads, then name, with unmeasured values last. A library counts downloads over 30 days. An app counts binary downloads per release. An app with none counts its crate downloads over 30 days. ML Rust runs this catalogue, so its closest project always gets a row.

Why ListedNo archive, New or Featured rule places it, so it is Listed.
What it lacks for Featured
- It has 3 active dependents and 3 new dependents in 365 days. Featured needs 11 active dependents or 9 new dependents in 365 days. The repository route reads 67 stars, 44 forks and 2 contributors. It needs 4,539 stars, 434 forks and 79 contributors together.
What else the check found
- The last activity is on 21 May 2026, 172 days ago. The rules expect an update within 365 days. Dormancy rule
