# **`repox::Entity Derive Attributes`**
> **Introduction**
>
> > `repox::Entity` is both a trait and a derive macro for the `repox`
> > framework. The `Entity` trait itself is very simple, requiring only
> > an `id` method that returns the entity's unique identifier. However,
> > the `Entity` derive macro provides tags which implement additional
> > functionality for the entity.
