//! This lib allow to access [Airparif](https://www.airparif.asso.fr/) indice pollution API for Ile-de-France (France).
//! It needs an [API key](https://www.airparif.asso.fr/rss/api) to work.
//!
//! Through the [client](./client/struct.RParifClient.html) it allows access to the following endpoints :
//! * indice : it provides the global pollution index
//! * indiceJour : it returns global and per pollutant indices for previous, current or next day
//! * idxville : returns indice and pollutant for given cities for previous, current and next day
//! * episode : returns pollution alerts
//!
//! # Examples
//!
//! Getting and displaying global pollution indices :
//! ```rust,no_run
//! use rparif::client::RParifClient;
//!
//! let client = RParifClient::new("my-api-key");
//! let indices = client.index()?;
//! for index in indices.into_iter() {
//!     println!("{}", index);
//! }
//! # Ok::<(), rparif::error::RParifError>(())
//! ```
//!
//! Fetching pollution alert :
//! ```rust,no_run
//! use rparif::client::RParifClient;
//!
//! let client = RParifClient::new("my-api-key");
//! let episodes = client.episode()?;
//! for episode in episodes.into_iter() {
//!     println!("{}", episode);
//! }
//! # Ok::<(), rparif::error::RParifError>(())
//! ```
