how to convert a number to a BitArray as fast as possible, given that the BitArray is already allocated to the needed length? Is bit checking the way to go, or is there a way to cast one to the other somehow?
Via bit checking I would end with this:
´´´
void assign(BitArray ba, size_t val) //@nogc
{
import std.algorithm : each;
assert(ba.length == size_t.sizeof * CHAR_BIT);
val.bitsSet.each!(b => ba.flip(b));
}
´´´
