map_rewire v0.1.1 MapRewire

Syntactic sugar to simply bulk rekey maps. MapRewire takes two arguments, data (map) and transformation (list of transformations / string of transformations separated by whitespace).

  1. Main Syntax: left<~>right (content<~>transformation). Left value is the map that holds the data and keys you would like to update, Right value is an Elixir List that contains a string for each of the keys that you would like to update.
  2. Transformation Syntax: left=>right (from=>to). Left is the original key, right is the new key.
  3. Return Syntax: [left, right] ([ original, rekeyed ]). left is the original map. right is the new, rekeyed, map.
