Carry

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

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

to the corresponding Elixir struct.

For example, given this struct:

  defmodule Instrument do
    defstruct [:carillon]
  end

by invoking the function:

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

We will get back:

%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.
