服务端 use std ::net::{TcpListener,TcpStream}; use std::thread; use std::time; use std::io; use std::io::{Read,Write}; fn handle_client(mut stream: TcpStream) -> io::Result<()>{ let mut buf = [0;512]; for _ in 0..1000{ let bytes_

变量和可变性 fn main() { let x = 5;//没加mut 属于不可变变量 println!("The value of x is: {}", x); x = 6;//程序运行到此次出现错误 println!("The value of x is: {}", x); } 变量和常量的区别 const MAX_POINTS: u32 = 100_000;声明常量使用 const 关键字而不是 let 隐藏 fn main(...

这是一个用rust编写的猜数字游戏。 use std::io; use rand::Rng; use std::cmp::Ordering; fn main() { println!("Guess the number!"); let secret_number = rand::thread_rng().gen_range(1,101); //println!("The secret number is:{}",secret_number); loop { ...
