    StridedLayout<dynamic_rank, offset_origin>& target);

Broadcasts source to target_shape.

Parameters:
StridedLayoutView<> source
StridedLayoutView<dynamic_rank, offset_origin> source

Source layout to broadcast.

span<const Index> target_shape

Target shape to which source will be broadcast.

Index *target_byte_strides

Pointer to array of length target_shape.size().

StridedLayout<> &target
StridedLayout<dynamic_rank, offset_origin> &target

Target layout to assign.

Returns:

For offset_origin overload, the offset in bytes of broadcasted array data pointer relative to source array data pointer.

Error absl::StatusCode::kInvalidArgument:

if the shapes are not compatible.
