//! `github-scopes-rs` Discover GitHub token scope permission and return you an easy interface for checking token permission before querying GitHub.
//!
//! In many cases, you try to do actions to GitHub, but you get unclear permissions errors. This project allows you to get which permission your token has before,
//! called GitHub, and if you don’t have the right permissions, you can tell the user the exact permission the user needs.
//!
//! ## How it works
//! We called Github api with the given token and get which permissions scope the token has in order the access to the API. Then, the permissions are being converted to a simple object that you can work with.
//! click [here](https://docs.github.com/en/developers/apps/building-oauth-apps/scopes-for-oauth-apps) read GitHub documentation.
//!
//! ## Get token permission
//! ```rust
//! use github_scopes_rs::oauth::OAuthContext;
//!
//! # fn run()  {
//! let permissions = OAuthContext::new("token").unwrap().get_scope_permissions();
//!
//! if !permissions.repo.all {
//!     // do something
//! }
//! # }
//! ```
