def self.zip(keys, values, default=nil, &block)

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)

end

#to_mash ⇒ Mash

Convert to Mash. This class has semantics of ActiveSupport's HashWithIndifferentAccess and we only have it so that people can write params[:key] instead of params['key'].

Returns:

  • (Mash) —

    This hash as a Mash for string or symbol key access.
