    assert_eq!(true, auth.verify(code, 0, 100));
}

TOTP example

use std::time::{SystemTime, UNIX_EPOCH};

use otpauth::TOTP;


fn main() {
    let auth = TOTP::new("python");
    let timestamp1 = SystemTime::now().duration_since(UNIX_EPOCH)?.as_secs();
    let code = auth.generate(30, timestamp1);
    let timestamp2 = SystemTime::now().duration_since(UNIX_EPOCH)?.as_secs();
    assert_eq!(true, auth.verify(code, 30, timestamp2));
}
