//! Wrapper for [Openlibrary's Web API](https://openlibrary.org/developers/api)
//!
//! # Overview
//!
//! **PLEASE NOTE**: this crate is currently in an experimental stage.
//! Meaning expect frequent, large breaking changes from version to version until we are in a stable state.
//!
//! There are currently 8 sub APIs offered by Openlibrary's Web API.
//! You can check the table below to see the status of each.
//!
//! - [X] [Books](https://openlibrary.org/dev/docs/api/books) [^books_completeness]
//! - [ ] [Authors](https://openlibrary.org/dev/docs/api/authors)
//! - [ ] [Subjects](https://openlibrary.org/dev/docs/api/subjects)
//! - [X] [Search](https://openlibrary.org/dev/docs/api/search)
//! - [ ] [Search inside](https://openlibrary.org/dev/docs/api/search_inside)
//! - [ ] [Partner](https://openlibrary.org/dev/docs/api/read)
//! - [ ] [Covers](https://openlibrary.org/dev/docs/api/covers)
//! - [ ] [Recent Changes](https://openlibrary.org/dev/docs/api/recentchanges)
//!
//! # Books
//!
//! You can view information about books by Works, Editions, and ISBN ids by using the [`books::Books`] struct
//!
//! ``` rust
//! use openlibrary_rs::books::{BookType, BooksBuilder};
//! use openlibrary_rs::OpenlibraryRequest;
//!
//! // execute request to Works API and pretty print debug of result
//! let books = BooksBuilder::default()
//!     .book_type(BookType::Works)
//!     .id("OL45883W")
//!     .build()
//!     .unwrap();
//!
//!     println!("{:#?}", books.execute());
//! ```
//!
//! # Search
//!
//! You can search for books, authors, and more using the [`search::Search`] struct
//!
//! ``` rust
//! use openlibrary_rs::search::SearchBuilder;
//! use openlibrary_rs::OpenlibraryRequest;
//!
//! // execute search and pretty print debug of first result
//! let search = SearchBuilder::default()
//!     .query("the lord of the rings")
//!     .build()
//!     .unwrap();
//!
//! println!("{:#?}", search.execute());
//! ```
//!
//! [^books_completeness]: Everything excluding the generic Books API is complete(i.e. Works, Editions, and ISBN APIs are done).
//!
