Functions
static void	report_size_overflow (size_t MinSize, size_t MaxSize)
	Report that MinSize doesn't fit into this vector's size type.

static void	report_at_maximum_capacity (size_t MaxSize)
	Report that this vector is already at maximum capacity.

template<class Size_T >
static size_t	getNewCapacity (size_t MinSize, size_t TSize, size_t OldCapacity)

static void *	replaceAllocation (void *NewElts, size_t TSize, size_t NewCapacity, size_t VSize=0)
	If vector was first created with capacity 0, getFirstEl() points to the memory right after, an area unallocated.

◆ replaceAllocation()

		size_t	VSize = `0`
	)

If vector was first created with capacity 0, getFirstEl() points to the memory right after, an area unallocated.

If a subsequent allocation, that grows the vector, happens to return the same pointer as getFirstEl(), get a new allocation, otherwise isSmall() will falsely return that no allocation was done (true) and the memory will not be freed in the destructor. If a VSize is given (vector size), also copy that many elements to the new allocation - used if realloca fails to increase space, and happens to allocate precisely at BeginX. This is unlikely to be called often, but resolves a memory leak when the situation does occur.
