iteraptor v0.5.0 Iteraptor.Iteraptable

use Iteraptor.Iteraptable inside structs to make them both Enumerable and Collectable:

defmodule Iteraptor.Struct do
  @fields [field: nil]

  def fields, do: @fields
  defstruct @fields

  use Iteraptor.Iteraptable
end

iex> %Iteraptor.Struct{field: 42}
...>   |> Enum.each(fn e -> Logger.debug(inspect(e)) end)
:ok

#⇒   {:field, 42}

Usage

Use the module within the struct of your choice and this struct will be automagically granted Enumerable and Collectable protocols implementations.

Summary

Macros

__using__(opts \\ [])

Allows to enable iterating features on structs with use Iteraptor.Iteraptable

Macros

__using__(opts \\ [])

Allows to enable iterating features on structs with use Iteraptor.Iteraptable

Parameters

opts: Keyword that currently might consist of skip: collectable to make Iteraptor to implement Enumerable protocol only

Examples

...>   |> Enum.map(fn {k, v} -> {k, v * 2} end)
...>   |> Enum.into(%Iteraptor.Struct{})
%Iteraptor.Struct{field: 84}
