=> true
irb(main):002:0> require 'sparsam'
=> true
irb(main):003:0> obj = MyStruct.new
=> #<MyStruct:0x007fa70d924148>
irb(main):004:0> serialized = obj.serialize # turn object into string
=> "\x00"
irb(main):005:0> obj2 = Sparsam::Deserializer.deserialize( MyStruct, serialized ) # deserialize string into obj
=> #<MyStruct:0x007fa70e3ee998>
