Submitted by Nidhi, on October 28, 2021

Problem Solution:

In this program, we will create an enum with two constants. Then we will convert the enum constants into an integer number.

Program/Source Code:

The source code to get the integer value of enum constants is given below. The given program is compiled and executed successfully.

// Rust program to get the integer value 
// of enum constants

#[derive(Debug)]

enum Gender {
   female,male
}

fn main() {
   println!("Male:   {:?}", Gender::male as i32);
   println!("Female: {:?}", Gender::female as i32);
}

Output:

Male:   1
Female: 0

Explanation:

In the above program, we created an enum Gender and function main(). The enum Gender contains two constants female and male.

In the main() function, we converted the enum constants into integers and printed the result.
