# Carry

Carry is a super simple, dependency free package that transforms a map in this
form:

```elixir
%{"carillon" => "sound", "marimba" => "percussion"}
```

to the corresponding Elixir `struct`.

For example, given this `struct`:

```elixir
  defmodule Instrument do
    defstruct [:carillon]
  end
```

by invoking the function:

```elixir
Carry.on(%{"carillon" => "sound", "marimba" => "percussion"}, %Instrument{})
```

We will get back:

```elixir
%Instrument{carillon: "sound"
```

This is usually useful when having a decoded payload from json (a map) and
we want to convert to an Elixir `struct.
