First Project

With Cargo

Create a new folder then setup a rust project with cargo init. This command will create Cargo.toml & src/main.rs with a Hello World example. Run the project with cargo run.

mkdir new-project

cd new-project

cargo init

cargo run

Without Cargo

Create a file named main.rs with:

fn main() {
  let hello = "Hello World";
  println!("{}", hello)
}

Compile it with rustc main.rs then run it with ./target/debug/main (.\target\debug\hello.exe on Windows)
