Known Subclasses:

String of fixed length. Default length is 0, so you must override this class and set the _len class variable.

>>> from tempfile import TemporaryFile
>>> f = TemporaryFile()
>>> class String8(FixedString):
...     _len = 8
>>> s = String8()
>>> if f.write('abcdefghij'.encode()): pass # ignore result for py3k
>>> if f.seek(0): pass # ignore result for py3k
>>> s.read(f)
>>> str(s)
'abcdefgh'
>>> if f.seek(0): pass # ignore result for py3k
>>> s.set_value('Hi There')
>>> s.write(f)
>>> if f.seek(0): pass # ignore result for py3k
>>> m = String8()
>>> m.read(f)
>>> str(m)
'Hi There'
