#![warn(missing_docs)]
//! Rusty-interaction is a library that allows you to work with Discord's new [Interactions](https://blog.discord.com/slash-commands-are-here-8db0a385d9e6).
//! It can expose types and provides helper functions to validate your Interactions.
//! It can optionally provide a handler that allows you to receive interactions via outgoing webhook.
//!
//! Note that Discord also has [official documentation](https://discord.com/developers/docs/intro).
//!
//! ## Examples
//! See the [`examples`](https://github.com/hugopilot/rusty-interaction/tree/main/examples) directory.
