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)
