(i32, f64, u8) = (500, 6.4, 1); } tup 变量绑定到整个元组上，因为元组是一个单独的复合元素。为了从元组中获取单个值，可 以使用模式匹配（pattern matching）来解构（destructure）元组值，像这样： 文件名：src/main.rs fn main() { let tup = (500, 6.4, 1); let (x, y, 解构（destructuring），因为它将一个元组拆成了三个部 分。最后，程序打印出了 y 的值，也就是 6.4。 我们也可以使用点号（.）后跟值的索引来直接访问所需的元组元素。例如： 文件名：src/main.rs fn main() { let x: (i32, f64, u8) = (500, 6.4, 1); let five_hundred = x.0; let six_point_four
