# 👤 oauth-lib

Asynchronous Rust library to deal with OAuth flows.

## Features

- Implements the ***OAuth 2.0** Authorization Code Grant* flow from [RFC6749](https://datatracker.ietf.org/doc/html/rfc6749#section-4.1)
- Implements the ***OAuth 2.0** Refresh Access Token* flow from [RFC6749](https://datatracker.ietf.org/doc/html/rfc6749#section-6)
- Supports **tokio** and **async-std** async runtimes
- Supports **rustls** and **native-tls** crypto libs

The library comes with 5 [cargo features](https://doc.rust-lang.org/cargo/reference/features.html), including 2 default ones:

- **`tokio`**: enables the [tokio](https://crates.io/crates/tokio) async runtime
- `async-std`: enables the [async-std](https://crates.io/crates/async-std) async runtime
- **`rustls`**: enables the [rustls](https://crates.io/crates/rustls) crypto
- `native-tls`: enables the [native-tls](https://crates.io/crates/native-tls) crypto
- `vendored`: compiles and statically link to a copy of non-Rust vendors like OpenSSL
