BloombergLP::bdlb::BitStringUtil::minusEqual

Bitwise MINUS the specified numBits of the specified srcBitString starting at the specified srcIndex from the numBits of the specified dstBitString starting at the specified dstIndex, and write the result over the bits that were read from dstBitString. The behavior is undefined unless dstBitString has a length of at least dstIndex + numBits and srcBitString has a length of at least srcIndex + numBits. Note that the logical difference A ‐ B is defined to be A & !B.
