Editing Serialization (section)

===Ruby===
[[Ruby programming language|Ruby]] includes the standard module <code>[https://docs.ruby-lang.org/en/master/Marshal.html Marshal]</code> with 2 methods <code>dump</code> and <code>load</code>, akin to the standard Unix utilities <code>[[dump (Unix)|dump]]</code> and <code>[[restore (program)|restore]]</code>. These methods serialize to the standard class <code>String</code>, that is, they effectively become a sequence of bytes. Some objects cannot be serialized (doing so would raise a <code>TypeError</code> exception): bindings, procedure objects, instances of class IO, singleton objects and interfaces. If a class requires custom serialization (for example, it requires certain cleanup actions done on dumping / restoring), it can be done by implementing 2 methods: <code>_dump</code> and <code>_load</code>. The [[instance method]] <code>_dump</code> should return a <code>String</code> object containing all the information necessary to reconstitute objects of this class and all referenced objects up to a maximum depth given as an integer parameter (a value of -1 implies that depth checking should be disabled). The [[class method]] <code>_load</code> should take a <code>String</code> and return an object of this class.
