serialization.rb

This Ruby code snippet demonstrates object serialization using Marshal.dump to convert a Ruby hash (person) into a byte string. This byte string is then written to a binary file named person.dat in the input/serialization directory. This process persists the Ruby object’s data to a file for later retrieval and deserialization.

Ruby code snippet

person = { name: "Alice", age: 30 }
#=> {name: "Alice", age: 30}
serialized_person = Marshal.dump(person)
#=> "\x04\b{\a:\tnameI\"\nAlice\x06:\x06ET:\bagei#"

File.open('input/serialization/person.dat', 'wb') do |file|
  file.write(serialized_person)
end
#=> 30
