//! # http_auth_basic
//!
//! HTTP Basic Authentication Scheme (RFC 7617 base64-encoded credentials) for Rust applications
//!
//! # Example
//!
//! Decoding a basic authorization value and creating a `Credentials` struct
//! from it
//!
//! ```
//! use http_auth_basic::Credentials;
//!
//! let auth_header_value = String::from("Basic dXNlcm5hbWU6cGFzc3dvcmQ=");
//! let credentials = Credentials::from_header(auth_header_value).unwrap();
//!
//! assert_eq!(credentials.user_id, String::from("username"));
//! assert_eq!(credentials.password, String::from("password"));
//! ```
//!
//! Encoding `Credentials` into a basic authorization header value.
//!
//! ```
//! use http_auth_basic::Credentials;
//!
//! let credentials = Credentials::new("username", "password");
//! let credentials = credentials.as_http_header();
//!
//! assert_eq!(String::from("Basic dXNlcm5hbWU6cGFzc3dvcmQ="), credentials);
//! ```
