3.3 Tuples

• Similar types include arrays and slices, but they are not commonly used in rust, and Vector is commonly used

tuple

• Store data anonymously
• Immutable

The usefulness of tuples

• function return
• extract variables

the code

fn a_tuple() -> (i32, i32) {
    
    
    (0, 1)
}

fn main() {
    
    
    println!("{:?}", a_tuple());
    let (a, b) = a_tuple();
    println!("a: {}, b: {}", a, b);
}
