Cargo is the Rust package manager. Cargo downloads your Rust package’s dependencies, compiles your packages, makes distributable packages, and uploads them to crates.io, the Rust community’s package registry. You can contribute to this book on GitHub.
To get started with Cargo, install Cargo (and Rust) and set up your first crate.
The guide will give you all you need to know about how to use Cargo to develop Rust packages.
The reference covers the details of various areas of Cargo.
