Attribrutal

Lazily coerced attributes

##Usage:

class MoreSpeed
  include Attribrutal::Model
  attribute :harder
  attribute :better
  attribute :faster
  attribute :stronger
end

##With coercion:

class MoreSpeed
  include Attribrutal::Model
  attribute :harder, Coercion::Integer
  attribute :better, Coercion::String
  attribute :faster, Coercion::Boolean
  attribute :stronger, MyAwesomeCoercion
end

##With defaults:

class MoreSpeed
  include Attribrutal::Model
  attribute :harder, Coercion::Integer, default: 10
  attribute :better, Coercion::String, default: "better"
  attribute :faster, Coercion::Boolean, default: true
  attribute :stronger, MyAwesomeCoercion
end

##Introspection

MoreSpeed.attributes return a hash of attribute names and their types

##Assignment

MoreSpeed.new harder: 30, better: "much"

##Getting at raw (uncoerced) attributes

MoreSpeed.new.raw_attributes

##Getting at coerced attributes

MoreSpeed.new.attributes

##Coercers

Implement your own, they should provide a class method coerce which takes two arguments; a value and a default and return the value coerced or the default, its all up to the coercer. You can implement any kind of additional meta information on the type.
