Simple sugar to make changing keys on maps less ugly.

What’s the why? When you consume information from a lot of API’s/sources, you get data streaming in with the keys from other applications, other applications naming conventions might not fit your app.

left <~> right, left is your map from outside your app, right is the rewrite rules.

It looks a little something like this: %{“id”=>”234923409”, “title”=>”asdf”}<~>[“title=>name”, “id=>shopify_id”]

Rewrite rules can be an Elixir List or a whitespace-separated list. They follow a format of left=>right, left is the old key, and right representing the new.

Add it as a dep: {:map_rewire, “~> 0.1.0”}
