pub unsafe fn bitmap_and_owner<O>(
data: &[u8],
offset: usize,
length: usize,
owner: O,
) -> PolarsResult<BooleanArray>
Expand description
Creates a (non-null) BooleanArray
from a slice of bits.
This does not have memcopy and is the fastest way to create a BooleanArray
.
This can be useful if you want to apply arrow kernels on slices without incurring a memcopy cost.
The offset
indicates where the first bit starts in the first byte.
ยงSafety
The caller must ensure the passed owner
ensures the data remains alive.
