元组(Tuples)
fn main() {
let t: (i8, bool) = (7, true);
println!("t.0: {}", t.0);
println!("t.1: {}", t.1);
}

和数组一样,元组也具有固定的长度。
元组将不同类型的值组成一个复合类型。
元组中的字段可以通过英文句号加上值的下标进行访问比如:
t.0
,t.1
。The empty tuple
()
is referred to as the “unit type” and signifies absence of a return value, akin tovoid
in other languages.
