Intro To Rust

First, you have to install the Rust tools to be able to compile Rust code. In order to do that, go to rustup.rs

Cargo is one of the tools you use in Rust. It is used to control your Rust project. It will build and compile your program

When in our projects root folder, cargo build will build our code into an executable program. cargo run will build and run our program.

In the file src/main.rs, we can add our first bits of code.

When you first open up src/main.rs, you should see this code already in the file.

fn is the word in Rust we use to define a function. main() is the name of our function. The curly brackets will contain the code of our function. The main() function is automatically executed when we run our program.

The first program we make will display a message to the screen. The function println!() will be used to acheive our goal. Inside the brackets, we will add our message.

So our code should look like this:

After each expression, we end our line with a semi-colon.

With Rust installed, we can move on to learn more about programming!
