Let's declare a variable in Rust: `let x = 5;`" - 我们在Rust中声明一个变量：`let x = 5;`
In Rust, functions start with the `fn` keyword, like `fn hello() { println!("Hello, world!"); }`" - 在Rust中，函数以`fn`关键字开始，如`fn hello() { println!("Hello, world!"); }`
Rust is a statically typed language, so you must specify types: `let name: String = "Alice".to_string();`" - Rust是静态类型语言，所以必须指定类型：`let name: String = "Alice".to_string();`
Rust uses ownership and borrowing to manage memory, like `let mut y = x;` creates a mutable borrow." - Rust使用所有权和借用来管理内存，如`let mut y = x;`创建了一个可变借用。
To create an array in Rust, you write `let numbers: [i32; 5] = [1, 2, 3, 4, 5];`" - 在Rust中创建数组，你这样写：`let numbers: [i32; 5] = [1, 2, 3, 4, 5];`
Rust has enums for creating algebraic data types, like `enum Color { Red, Green, Blue }`" - Rust通过枚举（enums）来创建代数数据类型，如`enum Color { Red, Green, Blue }`
Structs in Rust define custom data types, e.g., `struct Person { name: String, age: u8 }`" - Rust中的结构体（structs）用于定义自定义数据类型，例如`struct Person { name: String, age: u8 }`
Error handling in Rust is done with `Result`, as in `fn read_file() -> Result`" - Rust通过`Result`进行错误处理，如`fn read_file() -> Result`
Rust's match keyword is a powerful pattern matching construct, like `match x { 1 => println!("One"), _ => println!("Other") }`" - Rust的`match`关键字是一个强大的模式匹配构造，如`match x { 1 => println!("One"), _ => println!("Other") }`
Rust has a concept of ' Traits' for defining behavior, e.g., `impl Clone for MyType { fn clone(&self) -> Self { ... } }`" - Rust有“Traits”的概念，用于定义行为，例如`impl Clone for MyType { fn clone(&self) -> Self { ... } }`
