Add destructure structs feature

[muhifauzan]

Closes #2.

[muhifauzan]

Need help beforehand, @danielberkompas how to move the test do doctest for this case? I try to move the module definition for Person but no luck. Seems like the module definition in doctest doesn't reference the module in the test namespace, and use the lib namespace instead.

@muhifauzan Try this?

defmodule DestructureTest do
  use ExUnit.Case

  import Destructure

  defmodule Person do
    defstruct [:name, :email]
  end

  doctest Destructure

  test "destructure a simple structs" do
    d(%Person{name}) = %Person{name: "Joe"}
    assert name == "Joe"
  end

  test "destructure a simple struct with custom variable naming" do
    d(%Person{name, email: mail}) = %Person{name: "Joe", email: "[email protected]"}
    assert {name, mail} == {"Joe", "[email protected]"}
  end
end

Defining the Person module above the doctest call should make it available in doctests.

Ah, I see. I'll try to implement that later.
