//!
//! A library to work with Javascript Object Signing and Encryption(JOSE),
//! including JSON Web Tokens (JWT), JSON Web Signature (JWS) and JSON Web Encryption (JWE)
//!
//! This was based off [`Keats/rust-jwt`](https://github.com/Keats/rust-jwt).
//!
//! ## Installation
//!
//! Add the following to Cargo.toml:
//!
//! ```toml
//! biscuit = "0.7.0"
//! ```
//!
//! To use the latest `master` branch, for example:
//!
//! ```toml
//! biscuit = { git = "https://github.com/lawliet89/biscuit", branch = "master" }
//! ```
//!
//! See [`JWT`] for common usage examples.
//!
//! ## Supported Features
//! The crate does not support all, and probably will never support all of
//! the features described in the various RFCs, including some algorithms and verification.
//!
//! See the [documentation](https://github.com/lawliet89/biscuit/blob/master/doc/supported.md) for more information.
//!
