EtsHelper

EtsHelper is a wrapper of ETS. It does not try to wrap all the functionality, only those functions that are constantly used in Elixir projects. It also includes some new functions. This is a library that could be improved in the future if it is required by new needs.

Installation

Add ets_helper to your list of dependencies in mix.exs:

  def deps do
    [{:ets_helper, "~> 0.1.0"}]
  end
