Rust by Example: Compound Types - Tuples

Tuples are a general way of grouping together a number of values with a variety of types into one compound type. Tuples have a fixed length: once declared, they cannot grow or shrink in size.
Run code Copy code 
fn main() {

Here we create a tuple type with elements of different types and then we destructure it into three variables.

 
    let tup: (i32, f64, u8) = (500, 6.4, 1);
    let (x, y, z) = tup;
    println!("x: {}, y: {}, z: {}", x, y, z);

We can also access a tuple element directly by using a period followed by the index of the value we want to access.

 
    let five_hundred = tup.0;
    let six_point_four = tup.1;
    let one = tup.2;
    println!("five_hundred: {}", five_hundred);
    println!("six_point_four: {}", six_point_four);
    println!("one: {}", one);
}

$ rustc tuples.rs
$ ./tuples
x: 500, y: 6.4, z: 1
five_hundred: 500
six_point_four: 6.4
one: 1
