std::size_t
num0(
std::size_t begin = 0,
std::size_t end = k_INVALID_INDEX) const;Return the number of bits in the range optionally specified by begin and end having a value of 0. The range is [begin .. effectiveEnd)], where effectiveEnd == length() if end is not specified and effectiveEnd == end otherwise. The behavior is undefined unless begin <= effectiveEnd <= length().
