Installing Rust and Setting Up Your Environment

Before writing Rust code, you need to install Rust and set up your development environment.

1. Install Rust:

Use the official installer rustup which installs Rust, Cargo (Rust’s package manager), and related tools.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

After installation, run:

rustc --version

to verify Rust is installed.

2. Set Up an IDE:

• VS Code: Install the rust-analyzer extension for autocompletion, type checking, and more.
• IntelliJ Rust: JetBrains’ Rust plugin for IntelliJ-based IDEs.

3. Create a New Project:

cargo new hello_rust

This creates a new project with a main.rs file and a Cargo.toml file to manage dependencies.
