Usage

dumps(obj)

Return the shibazuke representation of the object as a string.

loads(string)

Read a shibazuke object hierarchy from a string.

Exapmle

Here’s simple example of shibazuzke:

>>> import shibazuke
>>> data = ['abc', {1:(2,3,4)}]
>>> result = shibazuke.dumps(data)
>>> data == shibazuke.loads(result)
True

Limitations

• Following type of Python objects could be serialized.

  int, long, str, unicode, tuple, list, dict

• Number of objects to be serialized is limited to 2147483647.

• Length of serialized string is limited to 2147483647.

• Max depth of object graphs is limited to 100, and circular reference is not supported.

  >>> import shibazuke
  >>> list1 = []
  >>> list2 = [list1]
  >>> list1.append(list2)
  >>> shibazuke.dumps(list1)

• Objectes can occur multiple times in the object tree to be serialized, but they are de-serialized as differect objects.

  >>> import shibazuke
  >>> list1 = []
  >>> list2 = [list1, list1]
  >>> result = shibazuke.dumps(list2)
  >>> serialized = shibazuke.loads(result)
  >>> serialized[0] is serialized[1]
  False
