Rust Installation
Install Rust and Create a First Project
First, install Rustup⮳.
On Linux, macOS, or other Unix-like systems (including Windows Subsystem for Linux - WSL), open your terminal and run the following command:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
This command downloads a script and starts the rustup installation. Follow the on-screen prompts.
After installation, rustup might ask you to configure your current shell. You can either restart your terminal or run the command provided by the installer (usually something like source $HOME/.cargo/env on Unix-like systems).
On Windows, it's recommended to visit the official Rust website's installation page and download the rustup-init.exe installer. Running this executable will guide you through the installation. You may also need the C++ build tools for Visual Studio, which the installer can help you set up.
Second, check whether you have Rust installed correctly. Open a new terminal window and check if Rust is installed correctly by running:
rustc --version
cargo --version
These commands should print the installed versions of the Rust compiler (rustc) and the Rust package manager and build tool (cargo).
Third, open the documentation, if needed. You can open the locally installed Rust documentation in your web browser using:
rustup doc
Fourth, you can start creating projects using cargo new and build/run them with cargo build and cargo run.
- Create a new project.
cargo new hello_world
cd hello_world
code . # open VS Code (or your favorite editor) and edit the code as you wish.
- Build / run the code.
cargo check # check if the code can compile.
cargo build # compile.
cargo run # run the executable.
cargo run builds the code if cargo build has not been invoked before or the code has changed.
