Rails - Jan 2006 - where is the ActionStruct::Base in rails???

there is a example in

http://api.rubyonrails.com/classes/ActionWebService/Base.html

and it mentioned
<code>
class SearchCriteria < ActionStruct::Base
    member :firstname, :string
    member :lastname,  :string
    member :email,     :string
end
</code>

but i can not find ActionStruct''s source code in the rails''s 
distribution,and i found ''NameError: uninitialized constant 
ActionStruct'' when using it

should it be ActionWebService::Struct ?

Maybe it''s a type error ?

I also find the example in
http://api.rubyonrails.com/classes/ActionWebService/Invocation/ClassMethods.html
<code>
 class CustomService < ActionWebService::Base
    before_invocation :intercept_add, :only => [:add]

    def add(a, b)
      a + b
    end

    private
      def intercept_add
        return [false, "permission denied"] # cancel it
      end
  end
</code>
can''t work at all

The method intercept_add need declare two parameters otherwise rails 
will report "wrong number of arguments (2 for 0)"

my environment is rails 1.0 ,ruby 1.8.2, windows xp sp2

Not so.  I''m using 1.8.2 on OS X 10.9.3, Windows 2000 and Debian
without
problems.  The site says 1.8.3 is duff, though...
