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)
