//! A fully generated, opinionated API client library for Ramp.
//!
//! [![docs.rs](https://docs.rs/ramp-api/badge.svg)](https://docs.rs/ramp-api)
//!
//! ## API Details
//!
//! Ramp's developer API makes it easier for companies to programmatically set up and manage their card program.
//!
//! It provides the ability to automate card issuing and the ability to integrate features like reporting with other software platforms.
//!
//! [API Terms of Service](https://ramp.com/developer-agreement)
//!
//!
//!
//!
//! ## Client Details
//!
//! This client is generated from the [Ramp OpenAPI
//! specs](https://github.com/sumatokado/ramp-developer) based on API spec version `1.0`. 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]
//! ramp-api = "0.2.6"
//! ```
//!
//! ## Basic example
//!
//! Typical use will require intializing a `Client`. This requires
//! a user agent string and set of credentials.
//!
//! ```
//! use ramp_api::Client;
//!
//! let ramp = Client::new(
//!     String::from("client-id"),
//!     String::from("client-secret"),
//!     String::from("redirect-uri"),
//!     String::from("token"),
//!     String::from("refresh-token"),
//! );
//! ```
//!
//! Alternatively, the library can search for most of the variables required for
//! the client in the environment:
//!
//! - `RAMP_CLIENT_ID`
//! - `RAMP_CLIENT_SECRET`
//! - `RAMP_REDIRECT_URI`
//!
//! And then you can create a client from the environment.
//!
//! ```
//! use ramp_api::Client;
//!
//! let ramp = Client::new_from_env(String::from("token"), String::from("refresh-token"));
//! ```
//!
//! It is okay to pass empty values for `token` and `refresh_token`. In
//! the initial state of the client, you will not know these values.
//!
//! To start off a fresh client and get a `token` and `refresh_token`, use the following.
//!
//! ```
//! use ramp_api::Client;
//!
//! async fn do_call() {
//!     let mut ramp = Client::new_from_env("", "");
//!
//!     // Get the URL to request consent from the user.
//!     // You can optionally pass in scopes. If none are provided, then the
//!     // resulting URL will not have any scopes.
//!     let user_consent_url = ramp.user_consent_url(&["some-scope".to_string()]);
//!
//!     // In your redirect URL capture the code sent and our state.
//!     // Send it along to the request for the token.
//!     let code = "thing-from-redirect-url";
//!     let state = "state-from-redirect-url";
//!     let mut access_token = ramp.get_access_token(code, state).await.unwrap();
//!
//!     // You can additionally refresh the access token with the following.
//!     // You must have a refresh token to be able to call this function.
//!     access_token = ramp.refresh_access_token().await.unwrap();
//! }
//! ```
