引言

Rust,作为一种体系编程言语,以其内存保险、并发高效跟机能优胜等特点,在频年来遭到了广泛关注。对想要深刻进修Rust编程的开辟者来说,实战挑衅是晋升技能的重要道路。本文将带你从入门到粗通,经由过程一系列实战困难,解锁Rust编程的奥秘。

一、Rust编程入门

1.1 进修资本

1.2 线下培训上风

二、Rust编程进阶

2.1 高等特点

2.2 实战案例

2.2.1 Web开辟

2.2.2 嵌入式体系

2.2.3 游戏开辟

三、Rust编程实战挑衅

3.1 编写一个简单的Web效劳器

use std::net::TcpListener;
use std::io::{Write, BufReader, BufWriter};

fn main() -> io::Result<()> {
    let listener = TcpListener::bind("127.0.0.1:7878")?;
    for stream in listener.incoming() {
        handle_connection(stream?)?;
    }
    Ok(())
}

fn handle_connection(mut stream: TcpStream) -> io::Result<()> {
    let mut buf_reader = BufReader::new(&stream);
    let mut buf = Vec::new();
    buf_reader.read_to_end(&mut buf)?;

    let response = "HTTP/1.1 200 OK\r\n\r\nHello, world!";
    stream.write_all(response.as_bytes())?;

    Ok(())
}

3.2 实现一个冒泡排序算法

fn bubble_sort<T: Ord>(arr: &mut [T]) {
    let len = arr.len();
    for i in 0..len {
        for j in 0..(len - i - 1) {
            if arr[j] > arr[j + 1] {
                arr.swap(j, j + 1);
            }
        }
    }
}

fn main() {
    let mut numbers = vec![3, 2, 1];
    bubble_sort(&mut numbers);
    println!("{:?}", numbers);
}

3.3 开辟一个简单的命令行东西

use std::fs::File;
use std::io::{self, Read, Write};
use std::process;

fn main() -> io::Result<()> {
    let args: Vec<String> = process::args().collect();
    if args.len() < 3 {
        eprintln!("Usage: {} <command> <file>", args[0]);
        process::exit(1);
    }

    let command = &args[1];
    let file_path = &args[2];

    match command.as_str() {
        "compress" => compress_file(file_path)?,
        "decompress" => decompress_file(file_path)?,
        _ => {
            eprintln!("Unknown command: {}", command);
            process::exit(1);
        }
    }

    Ok(())
}

fn compress_file(file_path: &str) -> io::Result<()> {
    let mut file = File::open(file_path)?;
    let mut compressed_data = Vec::new();
    file.read_to_end(&mut compressed_data)?;

    let compressed_file_path = format!("{}.gz", file_path);
    let mut compressed_file = File::create(&compressed_file_path)?;
    compressed_file.write_all(&compressed_data)?;

    Ok(())
}

fn decompress_file(file_path: &str) -> io::Result<()> {
    let mut compressed_file = File::open(file_path)?;
    let mut decompressed_data = Vec::new();
    compressed_file.read_to_end(&mut decompressed_data)?;

    let decompressed_file_path = format!("{}.decompressed", file_path);
    let mut decompressed_file = File::create(&decompressed_file_path)?;
    decompressed_file.write_all(&decompressed_data)?;

    Ok(())
}

四、总结

经由过程以上实战挑衅,你可能逐步晋升Rust编程技能,解锁更多实战困难。一直现实跟总结,信赖你将可能成为一名优良的Rust开辟者。
