//! A fully generated, opinionated API client library for Oxide.
//!
//! [![docs.rs](https://docs.rs/oxide-api/badge.svg)](https://docs.rs/oxide-api)
//!
//! ## API Details
//!
//! API for interacting with the Oxide control plane
//!

//!
//!
//!
//! ## Client Details
//!
//! This client is generated from the [Oxide OpenAPI
//! specs](https://github.com/oxidecomputer/omicron) based on API spec version `0.0.1`. This way it will remain
//! up to date as features are added. The documentation for the crate is generated
//! along with the code to make this library easy to use.
//!
//!
//! To install the library, add the following to your `Cargo.toml` file.
//!
//! ```toml
//! [dependencies]
//! oxide-api = "0.1.0-rc.38"
//! ```
//!
//! ## Basic example
//!
//! Typical use will require intializing a `Client`. This requires
//! a user agent string and set of credentials.
//!
//! ```
//! use oxide_api::Client;
//!
//! let oxide = Client::new(String::from("api-key"), String::from("host"));
//! ```
//!
//! Alternatively, the library can search for most of the variables required for
//! the client in the environment:
//!
//! - `OXIDE_TOKEN`
//! - `OXIDE_HOST`
//!
//! And then you can create a client from the environment.
//!
//! ```
//! use oxide_api::Client;
//!
//! let oxide = Client::new_from_env();
//! ```
