How can I get DataMapper to return a sepcific number of elements?

Question

say I have

class MyClass
  include DataMapper::Resource
  property :id, Serial
  property :my_property, Text
end

How can I make a call to return a maximum of 3 items
Such as

MyClass.all(:my_property => "some_text", :max => 3)

Where the :max => n would indicate return n items.

I'm pretty sure there exists a built in function for this but I can't find it. Thanks.

Use :limit

MyClass.all(:my_property => "some_text", :limit => 3)
