Set up a coercion rule such that any time the specified key is set it will be coerced into the specified class. Coercion will occur by first attempting to call Class.coerce and then by calling Class.new with the value as an argument in either case.
@param [Object] key the key or array of keys you would like to be coerced. @param [Class] into the class into which you want the key(s) coerced.
@example Coerce a "user" subhash into a User object
class Tweet < Hash include Hashie::Extensions::Coercion coerce_key :user, User end
Set up a coercion rule such that any time a value of the specified type is set it will be coerced into the specified class.
@param [Class] from the type you would like coerced. @param [Class] into the class into which you would like the value coerced. @option options [Boolean] :strict (true) whether use exact source class only or include ancestors
@example Coerce all hashes into this special type of hash
class SpecialHash < Hash include Hashie::Extensions::Coercion coerce_value Hash, SpecialHash def initialize(hash = {}) super hash.each_pair do |k,v| self[k] = v end end end
