read line rust

To read a line in Rust, you can use the std::io::stdin module to read input from the user. Here's an example code snippet:

use std::io;

fn main() {
    let mut input = String::new();
    match io::stdin().read_line(&mut input) {
        Ok(_) => {
            println!("You entered: {}", input);
        Err(error) => {
            println!("Error reading input: {}", error);

In this code, we first create a mutable input variable of type String to store the user's input. Then, we use io::stdin().read_line(&mut input) to read a line from the standard input and store it in the input variable. Finally, we print the input using println!("You entered: {}", input).

Please note that this code snippet assumes that you have already imported the std::io module. If you haven't, you can add use std::io; at the beginning of your Rust file.

I hope this helps! Let me know if you have any further questions.
