Rust:剑指C++

Rust：极富活力和前途的编程语言，剑指C++

今天开始学习Rust,马上要回去休息了，只贴上一段实例代码，在后续的学习中，会对这种语言进行一个详尽的介绍（学习中。。。。）。

extern crate rand;

use std::io;
use std::cmp::Ordering;
use rand::Rng;

fn main() {
	println!("This is the test for guessing number!");

	let secret_number = rand::thread_rng().gen_range(1,101);

	//println!("the secret_number is {}",secret_number);

	loop{
		println!("Please input your guess");

		let mut guess=String::new();

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

		let guess: u32 = match guess.trim().parse(){
			Ok(num) => num,
			Err(_) => continue,
		};

		println!("You guessed:{}",guess);

		match guess.cmp(&secret_number){
			Ordering::Less	=> println!("To small"),
			Ordering::Greater =>println!("Too big"),
			Ordering::Equal	=>{
				println!("You Win");
				break;
			}
		}
	}

}

据说这种语言编程效率很高，^_,学习学习！
