Function MakeZeroBitArray

postgres/parser/utils/bitarray.go:123–126

MakeZeroBitArray creates a bit array with the specified bit size.

(bitLen uint)

// MakeZeroBitArray creates a bit array with the specified bit size.
func MakeZeroBitArray(bitLen uint) BitArray {
	a, b := EncodingPartsForBitLen(bitLen)
	return mustFromEncodingParts(a, b)
}

// ToWidth resizes the bit array to the specified size.
// If the specified width is shorter, bits on the right are truncated away.
