Cargo Basics

Cargo is Rust's build system and package manager. It compiles your code, downloads dependencies, runs tests, and builds documentation.

• Comes bundled with the Rust toolchain
• Manages a project's Cargo.toml manifest
• Handles the whole build lifecycle for you

Use cargo new to scaffold a binary project. It creates a directory with a src/main.rs and a Cargo.toml.

• cargo new my_app makes a binary crate
• cargo new my_lib --lib makes a library crate
