Modules Use Example

• use std::f64::consts::PI allows us to just use the identifier PI in my main function

use std::f64::consts::PI;

fn main() {
    println!("Welcome to the playground!");
    println!("I would love a slice of {}!", PI);
}

• Multiple items can be referenced in a single module path as so

use std::f64::consts::{PI,TAU}
