Parameters

self: Self

Source

  pub fn count(self: Self) usize {
    const num_masks = (self.bit_length + (@bitSizeOf(MaskInt) - 1)) / @bitSizeOf(MaskInt);
    var total: usize = 0;
    for (self.masks[0..num_masks]) |mask| {
        // Note: This is where we depend on padding bits being zero
        total += @popCount(mask);
    }
    return total;
