So you've decided to venture into the world of Rust! Great choice! Before you can begin writing elegant, memory-safe, and concurrent code, you'll need to install the Rust compiler and essential tools. Don't worry, it's a breeze!
Step 1: Downloading Rustup
The first thing you'll need to do is download Rustup, the Rust toolchain installer. Rustup manages your Rust installation, keeps it up-to-date, and helps you easily switch between different Rust versions. To download Rustup, visit the official Rust website and follow the instructions for your operating system.
For example, on Linux or macOS, you can run this command in your terminal:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
On Windows, you'll need to download and run the .exe installer instead.
Step 2: Installing the Rust Toolchain
Once Rustup is installed, it will automatically download and install the latest stable Rust toolchain. The toolchain includes the rustc compiler, cargo (the Rust package manager), and rust-docs (the Rust documentation).
During the installation process, you'll be prompted to select the default host triple (the target platform). You can usually just press "Enter" to accept the default option, but if you need a specific target, you can choose it from the list provided.
Step 3: Configuring Your Environment
After the toolchain is installed, you'll need to configure your environment so that you can access the Rust tools from your terminal.
For Linux and macOS users, Rustup should automatically add the necessary configuration to your shell profile. You might need to restart your terminal or run the following command to apply the changes:
source $HOME/.cargo/env
For Windows users, Rustup will configure your %PATH% environment variable. You might need to restart your terminal or computer for the changes to take effect.
Step 4: Verifying Your Installation
Now that you've installed Rust and configured your environment, it's time to make sure everything works as expected. Open a new terminal and run the following command:
rustc --version
You should see the Rust compiler version displayed, like so:
rustc 1.58.0 (abcdef01 2022-01-01)
Congratulations! You've successfully installed Rust and are now ready to start your journey towards becoming a fearless Rustacean. Your next step could be learning about Rust variables or diving into Rust functions. Enjoy the adventure!
