Struct Base64URLDecoder 

pub struct Base64URLDecoder;

The base64_url decoder, call: let base64_url_decoder = Decoder::<Base64URLDecoder>::new() to create a new instance And then call: result = base64_url_decoder.crack(input) to decode a base64_url string The struct generated by new() comes from interface.rs

use ares::decoders::base64_url_decoder::{Base64URLDecoder};

let decode_base64_url = Decoder::<Base64URLDecoder>::new();
let athena_checker = Checker::<Athena>::new();
let checker = CheckerTypes::CheckAthena(athena_checker);

let result = decode_base64_url.crack("aHR0cHM6Ly93d3cuZ29vZ2xlLmNvbS8_ZXhhbXBsZT10ZXN0", &checker).unencrypted_text;
assert!(result.is_some());
