Overview

Hashinator creates a Hasher from an Enumerable on [key, value] pairs. The Hashinator reflects changes to the underlying Enumerable.

Examples:

base = [[:a, 1], [:b, 2]]
hash = Hashinator.new(base)
hash[:a] #=> 1
base.first[1] = 3
hash[:a] #=> 3

Instance Method Summary

• #each ⇒ Object
• #initialize(enum) ⇒ Hashinator constructor

  A new instance of Hashinator.
