Rust - read input from STDIN

• std::io

• String

• stdin

• read_line

• expect

• Module std::io

• String::new() - Creates a new mutable empty string

• &mut name passes a reference of the variable to the function as mutable variable. & indicates it is a reference.

• read_line reads a line from the command line

use std::io;

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

    println!("Please type in your name:");
    io::stdin()
        .read_line(&mut name)
        .expect("Failed to get input");

    println!("Hello {}, how are you?", name);
}

Please type in your name:
Foo Bar
Hello Foo Bar
, how are you?

Two problems:

• The response looks broken. It has a newline after the name.
• After the prompt the program waits on a new line.
