Let us get started with Hello World code in Rust Programming Language.

Install Rust compiler and tools

Install Rust on Linux / Ubuntu as follows:

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

The above command will download rustup-init.sh file on your system and run it which will install all essential Rust tools include rustc which is the Rust compiler.

To install Rust on Windows, download rustup-init.sh file at following URL:

https://static.rust-lang.org/rustup/dist/i686-pc-windows-gnu/rustup-init.exe

Once downloaded, double click the rustup-init.exe file and all Rust tools will be installed.

Hello World in Rust

Follow the following steps to create and run Hello World code in Rust:

  • Create a new file and name it as "hello.rs". All Rust code has an extension .rs.
  • Edit the file and add the following code in it:
// Hello World code in Rust
fn main() {
  println!("Hello World");
}

This above code is the Hello World code in Rust. It will simply print "Hello World" in the terminal.

  • Go to the terminal and go to the directory where your code hello.rs is stored.

  • Type the following command in the terminal.

rustc hello.rs

This will create an executable named hello.exe in the current working directory.

  • Run the executable using the following command:
./hello.exe

The output will be displayed on the terminal. It will be:

Hello World
