About
faer is a rust crate that implements low level linear algebra routines and a high level wrapper for ease of use, in pure rust.
the aim is to provide a fully featured library for linear algebra with focus on portability, correctness, and performance.
see the official website and the docs.rs documentation for code examples and usage instructions.
questions about using the library, contributing, and future directions can be discussed in the zulip server.

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 FeaturedIt passes every Featured gate.
What it meets
- It has 150 active dependents and 126 new dependents in 365 days. Featured needs 11 active dependents or 9 new dependents in 365 days.
- Active dependents are at 100% of their peak. Featured needs at least 50%.
- Docs are present. The release commit or a manifest ties the crate to the repository.
- No vulnerability advisory stays unpatched past the grace window. At least one version is neither a prerelease nor 0.0.x.
- The last activity is on 24 Jun 2026, 138 days ago. The rules expect an update within 1800 days. Dormancy rule
Check notes
- repo host codeberg.org has no facts source: repository signals unknown
- the repo manifest faer/Cargo.toml declares the crate, and no release commit proves the link
Exact rules: Featured library. The check on applied thresholds version 9.
