网络安全大神Peter Parkanyi用Rust程序和eBPF来"窥探"Zoom程序的内容。最近Zoom因为新冠病毒而大火一把，而且又因为美国政府担心Zoom的服务器绕中国一圈再回到美国引发安全顾虑又大火一把。这个博文值得关注。

​​rust​​语言学习笔记：理解​​structs​​


Understanding rust lang - structs notes

​​https://www.staszewski.me/rust-struct-notes/​​


波兰小伙子​​Kamil Staszewski​​ 的Rust语言学习笔记。

什么是​​struct​​：

​​struct​​可以让我们创建有内容的数据结构，​​struct​​数据结构的写法有点类似​​Typescript​​语言中的​​interface​​接口， 当然很多别的编程语言的接口的实现也很类似：

​​struct Player {
name: String,
health: u32,
mana: u32,
}​​

要实现一个​​struct​​我们就要给它创建一个实例，我们依照它的定义用K/V方式给它赋值：

​​let player1 = Player {
name: String::from("Kamil"),
health: 100,
mana: 100,
};​​

至此，我们还不能直接用​​println!​​宏来打印出来，否则会遇到​​Player doesn't implement std::fmt::Display: Player cannot be formatted with the default formatte​​这样的错误。因为这里​​struct​​还没有实现它的​​trait​​，这就需要我们参照官方文档自己来实现一个。我们可以加这样的注释​​#[derive(Debug)]​​也可以用缺省的格式​​:?​​，或者在​​println!​​宏里面用花括号来表示缺省格式。然后我们可以试一试：


#[derive(Debug)] // annotation
struct Player {
    name: String,
    health: u32,
    mana: u32,
}


let player1 = Player {
    name: String::from("Kamil"),
    health: 100,
    mana: 100,
};


println!("Players data {:?}, player1);


怎么更新数据：


let player1 = Player {
    name: String::from("Kamil"),
    health: 100,
    mana: 100,
};


let player2 = Player {
    name: String::from("Gustav"),
    ..player1
}; // player2 has the same health and mana values as player1


也可以直接给实例的某个键赋值，不过要记得加上​​mut​​关键字保证数据结构的实例可以更改：


let mut player1 = Player {
    name: String::from("Kamil"),
    health: 100,
    mana: 100,
};


player1.name = String::from("Some other name");


给数据结构​​struct​​添加函数（方法）：

rust语言添加函数非常方便，首先它又一个可以自引用的语法​​&self​​，这个跟JS的​​this​​和Python的​​self​​非常类似。 我们必须用​​impl​​关键字并加上数据结构的名字来'实现'实例，记住我们在函数内部用​​&self​​来应用数据机构本身：


struct Player {
    name: String,
    health: u32,
    mana: u32,
}


impl Player {
    fn multiply_by(&self, n: u32) -> u32 {
      self.health * n
    }
}


let player1 = Player {
    name: String::from("Kamil"),
    health: 100,
    mana: 100,
};


println!("Players multipied health {:?}", player1.multiply_by(3));
