Running the first hello world problem

• basic code

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

Cargo - Rust’s build system and package manager

• check if Cargo is installed

cargo --version

• Cargo expects your code to be inside src dir

• Cargo.toml is a configuration file

• Building and running a Cargo project

$ cargo build
   Compiling hello_world v0.0.1 (file:///home/yourname/projects/hello_world)
$ ./target/debug/hello_world
Hello, world!

//or

$ cargo run
     Running `target/debug/hello_world`
Hello, world!

• Cargo.lock - tracks the dependencies of the application

• Makes a complete Cargo project to hack on

cargo new hello_world --bin
