Makes your defstructs enumerable

MakeEnumerable

Makes your structures enumerable!

The MakeEnumerable module injects defimpl Enumerable for your structs, as structs are basically maps with special tag (member) __struct__. The module hides the tag __struct__ and delegates all other members to map to be Enumerable.

defmodule Bar do
  use MakeEnumerable
  defstruct foo: "a", baz: 10
end

iex> import Bar
iex> Enum.map(%Bar{}, fn({k, v}) -> {k, v} end)
[baz: 10, foo: "a"]
