Simple Memoization for Ruby 2.0+.
Differences between Memoist & Memoist2
Unlike Memoist, this is not a drop-in replacement for old ActiveSupport::Memoizable. Memoist will still work just fine for that if you're using Ruby 2.0+. This project, on the other hand, is just me playing using Module#prepend which makes this stuff very simple.
- Works on all Rubies.
- Is quite complicated.
- Has the exact same api as
- Only works on
Ruby >= 2.0.0.
- Is deliberately much simpler.
- Has a slightly different API that could totally change.
Memoize an instance method
class Foo include Memoist2 def bar sleep 1 && 2**10 end memoize :bar end
Memoize a class method
class Foo include Memoist2 def self.bar # something expensive end memoize_class_method :bar end
