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.

pounce New
Single-crate facade for POUNCE from Rust: re-exports the TNLP trait, the IpoptApplication driver, and the supporting types in one place (plus a prelude), with feature-gated modules for the convex/LP/QP, active-set QP, and sensitivity paths. |

Why ListedNo archive, New or Featured rule places it, so it is Listed.
What it lacks for Featured
- It has 9 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 6 stars, 9 forks and 6 contributors. It needs 4,539 stars, 434 forks and 79 contributors together.
What else the check found
- The last activity is on 20 Jun 2026, 142 days ago. The rules expect an update within 365 days. Dormancy rule
Exact rules: Listed, Featured library. The check on applied thresholds version 9.
