# Returns the result of converting the serialized data in source into a
|
|
# Ruby object (possibly with associated subordinate objects). source
|
|
# may be either an instance of IO or an object that responds to
|
|
# to_str. If proc is specified, each object will be passed to the proc, as the object
|
|
# is being deserialized.
|
|
#
|
|
# Never pass untrusted data (including user supplied input) to this method.
|
|
# Please see the overview for further details.

|
|
# If the <tt>freeze: true</tt> argument is passed, deserialized object would
|
|
# be deeply frozen. Note that it may lead to more efficient memory usage due to
|
|
# frozen strings deduplication:
|
|
#
|
|
# serialized = Marshal.dump(['value1', 'value2', 'value1', 'value2'])
|
|
#
|
|
# deserialized = Marshal.load(serialized)
|
|
# deserialized.map(&:frozen?)
|
|
# # => [false, false, false, false]
|
|
# deserialized.map(&:object_id)
|
|
# # => [1023900, 1023920, 1023940, 1023960] -- 4 different objects
|

#
|
|
# deserialized = Marshal.load(serialized, freeze: true)
|
|
# deserialized.map(&:frozen?)
|
|
# # => [true, true, true, true]
|
|
# deserialized.map(&:object_id)
|
|
# # => [1039360, 1039380, 1039360, 1039380] -- only 2 different objects, object_ids repeating
