//! This Rust crate can be used to interact with the Google Authenticator mobile app for 2-factor-authentication.
//! This Rust crates can generate secrets, generate codes, validate codes and present a QR-Code for scanning the secret.
//! It implements TOTP according to RFC6238
//!
//! # Examples
//!
//! ```
//!
//! use google_authenticator::GoogleAuthenticator;
//!
//! let secret = "I3VFM3JKMNDJCDH5BMBEEQAW6KJ6NOE3";
//!
//! let auth = GoogleAuthenticator::new();
//! let code = auth.get_code(secret,0).unwrap();
//! if auth.verify_code(secret, code.as_str(), 1, 0).unwrap() {
//!     println!("match!");
//! }
//!
//! ```
