pub fn select_zeros(
index: &[u64],
all_bits: BitsRef<'_>,
target_rank: u64,
) -> Option<u64>
Expand description
Find the position of an unset bit by its rank using the index (O(log n)).
Returns None
if no suitable bit is found. It is
always the case otherwise that rank_zeros(index, result) == Some(target_rank)
and get(result) == Some(false)
.
