Transformable

Transform arbitrary maps and keyword lists into structs.

Transformable is a wrapper around struct/2. Out of the box, it supports easily converting Maps and Keyword Lists into structs. Like with struct/2, only the keys in the struct will be pulled out of your initial data structure. Maps passed in can have either string or atom keys, but Transformable doesn't use the (unsafe) String.to_atom/1. Default values on the struct will be respected, or can be overriden.

Transformable is defined as a Protocol with implementations for Map and List. You can write your own implementation and use transform/2 to specify custom outputs.

Installation

Transformable is available on Hex. The package can be installed by adding transformable to your list of dependencies in mix.exs:

def deps do
  [
    {:transformable, "~> 0.2.0"}
  ]
end
