This example is not the traditional FizzBuzz Icon Link; instead it is the smart contract version! A script can call the fizzbuzz ABI method of this contract with some u64 value and receive back the result as an enum.

The format for custom structs and enums such as FizzBuzzResult will be automatically included in the ABI JSON so that off-chain code can handle the encoded form of the returned data.

contract;
 
enum FizzBuzzResult {
    Fizz: (),
    Buzz: (),
    FizzBuzz: (),
    Other: u64,
}
 
abi FizzBuzz {
    fn fizzbuzz(input: u64) -> FizzBuzzResult;
}
 
impl FizzBuzz for Contract {
    fn fizzbuzz(input: u64) -> FizzBuzzResult {
        if input % 15 == 0 {
            FizzBuzzResult::FizzBuzz
        } else if input % 3 == 0 {
            FizzBuzzResult::Fizz
        } else if input % 5 == 0 {
            FizzBuzzResult::Buzz
        } else {
            FizzBuzzResult::Other(input)
        }
    }
}
