Method And

libs/bits/bit_array.go:139–150

And returns a bit array resulting from a bitwise AND of the two bit arrays. If the two bit-arrys have different lengths, this truncates the larger of the two bit-arrays from the right. Thus the size of the return value is the minimum of the two provided bit arrays.
