//! OpenStack SDK in Rust.
//!
//! The goal of this project is to provide a simple API for working with
//! OpenStack clouds.
//!
//! # Usage
//!
//! Start with [authentication](auth/index.html), then create a
//! [Cloud](struct.Cloud.html) object and use it for OpenStack API calls.
//!
//! # Examples
//!
//! ## List servers
//!
//! Get authentication parameters from the environment and get UUIDs of all
//! servers.
//!
//! ```rust,no_run
//! extern crate openstack;
//!
//! fn get_server_uuids() -> openstack::Result<Vec<String>> {
//!     let os = openstack::Cloud::from_env()?;
//!     let server_names = os
//!         .list_servers()?
//!         .into_iter()
//!         .map(|server| server.id().clone())
//!         .collect();
//!     Ok(server_names)
//! }
//! # fn main() { get_server_uuids().unwrap(); }
//! ```
//!
//! ## Find images
//!
//! Find public images using Identity password authentication with the default region:
//!
//! ```rust,no_run
//! extern crate fallible_iterator;
//! extern crate openstack;
//!
//! use fallible_iterator::FallibleIterator;
//!
//! fn get_public_image_names() -> openstack::Result<Vec<String>> {
//!     let scope = openstack::auth::Scope::Project {
//!         project: openstack::IdOrName::from_name("project1"),
//!         domain: Some(openstack::IdOrName::from_id("default")),
//!     };
//!     let auth = openstack::auth::Password::new(
//!         "https://cloud.local/identity",
//!         "admin",
//!         "pa$$w0rd",
//!         "Default"
//!     )
//!     .expect("Invalid auth_url")
//!     .with_scope(scope);
//!
//!     let os = openstack::Cloud::new(auth);
//!     let image_names = os
//!         .find_images()
//!         .with_visibility(openstack::image::ImageVisibility::Public)
//!         .into_iter()
//!         // This `map` comes from fallible-iterator, thus the closure returns a `Result`.
//!         .map(|image| Ok(image.name().clone()))
//!         .collect()?;
//!     Ok(image_names)
//! }
//! # fn main() { get_public_image_names().unwrap(); }
//! ```
//!
//! Notice the difference between `list_*` methods (return a result with a vector) and `find_*`
//! methods (return a query builder that can be used to create a fallible iterator).
//!
//! ## Create server
//!
//! Create a server with authentication from a `clouds.yaml` file:
//!
//! ```rust,no_run
//! extern crate openstack;
//! extern crate waiter;
//!
//! // Required for the `wait` call.
//! use waiter::Waiter;
//!
//! fn create_server() -> openstack::Result<openstack::compute::Server> {
//!     openstack::Cloud::from_config("my-cloud-1")?
//!         .new_server("test-server-1", "x-large")
//!         .with_image("centos-7")
//!         .with_network("private")
//!         .with_keypair("default")
//!         .create()?
//!         .wait()
//! }
//! # fn main() { create_server().unwrap(); }
//! ```
//!
//! # Requirements
//!
//! This crate requires Rust 2022 edition and rustc version 1.56.0 or newer.
