Implementation

pub fn toggleAll(self: *Self) void {
    const bit_length = self.bit_length;
    // avoid underflow if bit_length is zero
    if (bit_length == 0) return;

    const num_masks = numMasks(self.bit_length);
    for (self.masks[0..num_masks]) |*mask| {
        mask.* = ~mask.*;
    }

    const padding_bits = num_masks * @bitSizeOf(MaskInt) - bit_length;
    const last_item_mask = (~@as(MaskInt, 0)) >> @as(ShiftInt, @intCast(padding_bits));
    self.masks[num_masks - 1] &= last_item_mask;
