Bringing Types Into Scope With the Use Keyword in Rust

Using ES modules in JavaScript, you would import something into a module like so:

import thing from "stuff";

We can achieve similar behavior with Rust types using the use keyword. In the example below, we're importing io from std.

use std::io;

fn main() {
    let mut guess = String::new();

    io::stdin()
        .read_line(&mut guess)
        .expect("Failed to read line");

    println!("{}", guess);
}
