Rust 编程语言
Rust是Mozilla开发的注重安全、性能和并发性的编程语言。创建这个新语言的目的是为了解决一个很顽疾的问题：软件的演进速度大大低于硬件的演进，软件在语言级别上无法真正利用多核计算带来的性能提升。Rust是针对多核体系提出的语言，并且吸收一些其他动态语言的重要特性，比如不需要管理内存，比如不会出现Null指针等等。
文档注释在大项目非常有用。当运行 Rustdoc, 这些都是编译到文档的注释。 它们被表示为 ///, 并由 Markdown 支持.
/// A human being is represented here
pub struct Person {
/// A person must have a name, no matter how much Juliet may hate it
name: String,
}
impl Person {
/// Returns a person with the name given them
///
/// # Arguments
///
/// * `name` - A string slice that holds the name of the person
///
/// # Example
///
/// ```
/// // You can have rust code between fences inside the comments
/// // If you pass --test to Rustdoc, it will even test it for you!
/// let person = Person::new("name");
/// ```
pub fn new(name: &str) -> Person {
Person {
name: name.to_string(),
}
}
/// Gives a friendly hello!
///
/// Says "Hello, [name]" to the `Person` it is called on.
pub fn hello(& self) {
println!("Hello, {}!", self.name);
}
}
fn main() {
let john = Person::new("John");
john.hello();
}
