Lib.rs

What is lib.rs?

Lib.rs is a catalog of programs and libraries written in the Rust programming language. It has all 29060 crates (minus spam) from the crates.io registry.

Why use lib.rs?

• lib.rs is fast. There's no JavaScript anywhere.

• It has more complete and accurate crate information than crates.io:

  • Finds missing READMEs and pulls in documentation from src/lib.rs
  • Automatically categorizes crates and adds missing keywords, to improve browsing by categories and keywords.
  • Accurately shows which dependencies are out of date or deprecated.
  • Shows size of each crate and its dependencies.
  • Highlights which crates require nightly compiler or use non-Rust code.
  • Automatically finds and credits co-authors based on git history.

• It has an advanced ranking algorithm which promotes stable, regularly updated, popuplar crates, and hides spam and abandoned crates.

• It has short URLs to open a crate page lib.rs/crate-name and search lib.rs?keyword.

• Shows similar/related crates on each crate page, so you can discover alternatives.

• Has a dark theme (it's automatic — requires Firefox or Safari, and the OS set to dark).

How to install the crates?

Library crates

Run once:

cargo install cargo-edit

and then to add a library to your project, run:

cargo add library-name-here

Application crates

Install Rust via Rustup. It's important to use rustup — Rust bundled with Linux distros (like Debian) is outdated and generally won't work. If you have installed Rust already, run rustup update.

To install an app, run:

cargo install -f app-name-here

This will install it in ~/.cargo/bin and make it available from the command line.
