# Estructura    [![Kantox ❤ OSS](https://img.shields.io/badge/❤-kantox_oss-informational.svg)](https://kantox.com/)  [![Test](https://github.com/am-kantox/estructura/workflows/Test/badge.svg)](https://github.com/am-kantox/estructura/actions?query=workflow%3ATest)  [![Dialyzer](https://github.com/am-kantox/estructura/workflows/Dialyzer/badge.svg)](https://github.com/am-kantox/estructura/actions?query=workflow%3ADialyzer)

**Extensions for _Elixir_ structures.**

## Installation

```elixir
def deps do
  [
    {:estructura, "~> 0.1"},
    # optionally you might want to add `boundary` library 
    # it is used by `estructura` and many other projects
    # more info: https://hexdocs.pm/boundary
    {:boundary, "~> 0.9", runtime: false}
  ]
end
```
I suggest adding [`boundary`](https://hexdocs.pm/boundary) as a dependency since that is used in this project.
