Function arrow2::bitmap::utils::count_zeros

pub fn count_zeros(slice: &[u8], offset: usize, len: usize) -> usize

Returns the number of zero bits in the slice offsetted by offset and a length of length.

Panics

This function panics iff (offset + len).saturating_add(7) / 8 >= slice.len() because it corresponds to the situation where len is beyond bounds.
