Подскажите документацию на sqlite3.Binary, sqlite3.Error и прочее в dir(sqlite3)

Если посмотреть при помощи dir(sqlite3) список методов, то получим нечто:

dir(sqlite3)

Подскажите, где найти документацию на верхнюю часть функций, не описанных в документации. Ну например sqlite3.Binary и sqlite3.Error встречаются в ответах на StackOverflow без пояснения, а понять что и как не могу - т.к. почитать негде. Был бы признателен за ссылку, поскольку help не очень продуктивен. Вот например:

 help(sqlite3.Binary)
Help on class memoryview in module builtins:

class memoryview(object)
 |  memoryview(object)
 |  
 |  Create a new memoryview object which references the given object.
 |  
 |  Methods defined here:
 |  
 |  __delitem__(self, key, /)
 |      Delete self[key].
 |  
 |  __enter__(...)
 |  
 |  __eq__(self, value, /)
 |      Return self==value.
 |  
 |  __exit__(...)
 |  
 |  __ge__(self, value, /)
 |      Return self>=value.
 |  
 |  __getattribute__(self, name, /)
 |      Return getattr(self, name).
 |  
 |  __getitem__(self, key, /)
 |      Return self[key].
 |  
 |  __gt__(self, value, /)
 |      Return self>value.
 |  
 |  __hash__(self, /)
 |      Return hash(self).
 |  
 |  __le__(self, value, /)
 |      Return self<=value.
 |  
 |  __len__(self, /)
 |      Return len(self).
 |  
 |  __lt__(self, value, /)
 |      Return self<value.
 |  
 |  __ne__(self, value, /)
 |      Return self!=value.
 |  
 |  __repr__(self, /)
 |      Return repr(self).
 |  
 |  __setitem__(self, key, value, /)
 |      Set self[key] to value.
 |  
 |  cast(self, /, format, *, shape)
 |      Cast a memoryview to a new format or shape.
 |  
 |  hex(self, /)
 |      Return the data in the buffer as a string of hexadecimal numbers.
 |  
 |  release(self, /)
 |      Release the underlying buffer exposed by the memoryview object.
 |  
 |  tobytes(self, /)
 |      Return the data in the buffer as a byte string.
 |  
 |  tolist(self, /)
 |      Return the data in the buffer as a list of elements.
 |  
 |  ----------------------------------------------------------------------
 |  Static methods defined here:
 |  
 |  __new__(*args, **kwargs) from builtins.type
 |      Create and return a new object.  See help(type) for accurate signature.
 |  
 |  ----------------------------------------------------------------------
 |  Data descriptors defined here:
 |  
 |  c_contiguous
 |      A bool indicating whether the memory is C contiguous.
 |  
 |  contiguous
 |      A bool indicating whether the memory is contiguous.
 |  
 |  f_contiguous
 |      A bool indicating whether the memory is Fortran contiguous.
 |  
 |  format
 |      A string containing the format (in struct module style)
 |      for each element in the view.
 |  
 |  itemsize
 |      The size in bytes of each element of the memoryview.
 |  
 |  nbytes
 |      The amount of space in bytes that the array would use in
 |      a contiguous representation.
 |  
 |  ndim
 |      An integer indicating how many dimensions of a multi-dimensional
 |      array the memory represents.
 |  
 |  obj
 |      The underlying object of the memoryview.
 |  
 |  readonly
 |      A bool indicating whether the memory is read only.
 |  
 |  shape
 |      A tuple of ndim integers giving the shape of the memory
 |      as an N-dimensional array.
 |  
 |  strides
 |      A tuple of ndim integers giving the size in bytes to access
 |      each element for each dimension of the array.
 |  
 |  suboffsets
 |      A tuple of integers used internally for PIL-style arrays.
