Function And

postgres/parser/utils/bitarray.go:434–440

And computes the logical AND of two bit arrays. The caller must ensure they have the same bit size.

(lhs, rhs BitArray)

// And computes the logical AND of two bit arrays.
// The caller must ensure they have the same bit size.
func And(lhs, rhs BitArray) BitArray {
	res := lhs.Clone()
	for i, w := range rhs.words {
		res.words[i] &= w
	}
	return res
}

// Or computes the logical OR of two bit arrays.
// The caller must ensure they have the same bit size.
