Symptom

You want to create a simple rust program with cargo

Cause

Rust is a relatively new system programming language and is easy to start with

Solution

In this example we use cargo. Cargo is rust's build system and package manager.

cargo new hello_world
cd hello_world

Now we take a look at src/main.rs

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

Cargo has generated a simple "Hello, world" program automatically. To run this example you can use:

cargo run

You should see the following output:

Have fun.
