Rust program to return multiple values from the function

Rust Function | Returning multiple values: Write an example to demonstrate the example of returning multiple values from the function.
Last Updated : October 09, 2021

Problem Statement

In this program, we will create a user-defined function to return multiple values to the calling function.

Program/Source Code

The source code to return multiple values from the function is given below. The given program is compiled and executed successfully.

// Rust program to return multiple values 
// from the function

fn myfun()->(i32,i32){
    return (10,20);
}

fn main() {
    let (num1,num2)=myfun();
    
    println!("Num1: {}",num1);
    println!("Num2: {}",num2);
}

Output

Num1: 10
Num2: 20

Explanation

In the above program, we created two functions myfun() and main(). The myfun() function is a user-defined function that returns two integer values to the calling function.

In the main() function, we called the myfun() function and get two integer numbers, and printed them.
