Installing Rust using rustup

  1. Open Terminal
    You can find Terminal in Applications > Utilities or search for it using Spotlight.

  2. Install rustup and Rust
    Run the following command to download and run the rustup installation script:

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

    The script will prompt you to proceed. Press 1 for the default installation.

  3. Configure Your Shell
    After installation, you may need to add Rust to your system PATH. The installer will provide a command similar to:

     source $HOME/.cargo/env

    Add this line to your shell configuration file (e.g., .zshrc, .bashrc, or .bash_profile) to make Rust available in future sessions.

  4. Verify Installation
    Check that Rust is installed correctly:

     rustc --version

    You should see the Rust compiler version if the installation was successful.

Using Homebrew to Install Rust

Alternatively, you can use Homebrew to install Rust, though rustup is generally recommended for easier updates and version management.

  1. Install Homebrew (if not already installed):

     /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

  2. Install Rust with Homebrew:

     brew install rust

  3. Verify Installation:

     rustc --version

Compiling Rust Code

  1. Write a Rust Program
    Create a file named main.rs with the following content:

     fn main() {
      println!("Hello, World!");
 }

  2. Compile the Program
    In the terminal, navigate to the directory containing your file and run:

     rustc main.rs

  3. Run the Compiled Program:

     ./main

This setup should get you started with Rust development on macOS. If you have any issues, feel free to ask!
