Rust总结：复合类型-元组

原文：https://course.rs/basic/compound-type/tuple.html

元组

元组（Tuple）的长度是固定的，元组中元素的顺序也是固定的

let tup: (i32, f64, u8) = (500, 6.4, 1);

解构

let tup = (500, 6.4, 1);
let (x, y, z) = tup;

访问

fn main() {
    let x: (i32, f64, u8) = (500, 6.4, 1);

    let five_hundred = x.0;

    let six_point_four = x.1;

    let one = x.2;
}

超长无法打印

fn main() {
    let too_long_tuple = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13);
    println!("too long tuple: {:?}", too_long_tuple);
}
