Rust Get Started

Get Started With Rust

Here, you can try Rust without installing anything.

The Online Rust Editor runs directly in your browser, and shows both the code and the result:

Code:

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

Result:

Hello World!

Install Rust

However, if you want to download and install rust, you can go to rust-lang.org and follow the instructions there.

Or, if you are using the terminal, you can run:

curl https://sh.rustup.rs -sSf | sh

Check Installation

After installing, check if Rust is installed correctly by running:

rustc --version

The output will look something like this, depending on your version number:

rustc 1.86.0 (05f9846f8 2025-03-31)

Create a New Project

Use Cargo to create a new Rust project:

cargo new my_project

The output will look something like this:

    Creating binary (application) `my_project` package

note: see more `Cargo.toml` keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

This creates a folder called my_project with the following files:

• Cargo.toml: Project settings
• src/main.rs: Main Rust file

The main.rs file contains this default code:

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

Build and Run the Project

Next, write the following code to go into the project folder:

cd my_project

Then build and run the project:

cargo run

The output should be:

Hello, world!

Congratulations! You have just run your first Rust program.
