Understanding Cargo.toml

Cargo.toml is the manifest file that defines your Rust project's metadata, dependencies, and build configuration. It tells Cargo how to compile your code and manage external crates.

[package]
name = "my_project"
version = "0.1.0"
edition = "2024"

[dependencies]
rand = "0.8"

The [package] section sets the project name, version, and Rust edition. The [dependencies] section lists external crates required to build your project.

Cargo.toml is the instruction manual for your Rust project. It tells the build tool what your project is called, which version it is, and which outside libraries you need to run. Think of it like a recipe card that lists all the ingredients before you start cooking.
