Managing Dependencies with Crates
Understand how Cargo manages external crates (libraries) and how to publish your own for community use.
What are Crates & Cargo?
In Rust, a crate is the fundamental unit of compilation and distribution. Think of it as a package or a library that contains your code.
Cargo is Rust's official package manager and build system. It handles everything from creating new projects to managing dependencies, compiling code, and running tests. It's your best friend for Rust development!
The `Cargo.toml` File
Every Rust project managed by Cargo has a Cargo.toml file in its root directory. This is your project's manifest file, written in TOML (Tom's Obvious, Minimal Language).
It defines metadata about your project and, most importantly, lists its dependencies.
