Overview

Somebody said, I won’t depend on ‘ActiveSupport` for one method. Ok these are two but still… taken from the [rails project](github.com/rails/rails/blob/master/activesupport/lib/active_support/core_ext/array/extract_options.rb)

Instance Method Details

#extractable_options? ⇒ Boolean

By default, only instances of Hash itself are extractable. Subclasses of Hash may implement this method and return true to declare themselves as extractable. If a Hash is extractable, Array#extract_options! pops it from the Array when it is the last element of the Array.

Returns:

  • (Boolean)
