  when :ruby
    return Marshal.dump(value)
  else
    return value
  end
end

#transform_key(key) ⇒ Object

Allows an adapter to transform the key to a safe representation for it's backend. For example, the key: '$*...123()%~q' is not a key for the file system, so the Cachetastic::Adapters::File class should override this to make it safe for the file system.
