Cargo – Rust package manager

Last Updated on March 7, 2026

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.

Cargo is distributed by default with Rust, so if you’ve got rustc installed locally you probably also have cargo installed locally.

This is free and open source software.

Performs the following tasks:

  • Introduces two metadata files with various bits of package information.
  • Fetches and builds your package’s dependencies.
  • Invokes rustc or another build tool with the correct parameters to build your package.
  • Introduces conventions to make working with Rust packages easier.
