Detailed Description

FixedBitmap is a bitset (bitmap) of fixed side, it's intended to be used with placement new on chunk of memory. It'll use following memory for data layout. As follows:

some memory char ​*buf = new char[64 *​ 1024];

const uint32_t bitsCount = 100;

placement new on this memory FixedBitmap* arr = new (buf) FixedBitmap(bitsCount);

you can get max requiredMemorySize by an bitMap to use memory left buf = buf + FixedBitmap<SomeClass>::requiredMemorySize(bitsCount);

buf:

+------------------------------------------------------------+ | uint32_t | word0 | word1 | word2 | ... | +------------------------------------------------------------+
