部分衛生的巨集。 • Rust 是多範式的語言。舉例來說，它具備強大的物件導向程式設計功能，雖然並非函式語言，卻涉及 各式各樣的函式概念。 5.2 變數 Rust provides type safety via static typing. Variable bindings are made with let: fn main() { let x: i32 = 10; println!("x: question about modifying a[3] can spark an interesting discussion, but the answer is that for memory safety reasons you cannot do it through a at this point in the execution, but you can read the data from developers have turned off some compiler safety features and have to write correct code by themselves. It means the compiler no longer enforces Rust's memory-safety rules. 174 30.2 對裸指標解參考 建立指標相當安全，不過對指標解參考就需要使用
