Welcome to Python-flavored Magnum! Please note that, while already being
rather stable, this functionality is still considered experimental and
some APIs might get changed without preserving full backwards compatibility.
StridedBitArrayView1D class
One-dimensional bit array view with stride information
Provides one-dimensional read-only view on a memory range with custom stride values. See StridedBitArrayView2D, StridedBitArrayView3D, StridedBitArrayView4D, MutableStridedBitArrayView1D and others for multi-dimensional and mutable equivalents.
Memory ownership and reference counting
Similarly to BitArrayView, the view keeps a reference to the
original memory owner object in the owner field. Slicing a view
creates a new view referencing the same original object, without any
dependency on the previous view. The owner is None if the view
is empty.
Methods

- Broadcast a dimension
- def expanded(self, dimension: int, size: typing.Tuple[int, int]) -> StridedBitArrayView2D
- Expand a dimension
- def expanded(self, dimension: int, size: typing.Tuple[int, int, int]) -> StridedBitArrayView3D
- Expand a dimension
- def expanded(self, dimension: int, size: typing.Tuple[int, int, int, int]) -> StridedBitArrayView4D
- Expand a dimension
- def flipped(self, dimension: int) -> StridedBitArrayView1D
