def andByteString(shouldPad: Boolean, lhs: ByteString, rhs: ByteString): ByteString

Bitwise logical AND for ByteStrings.

Bitwise logical AND for ByteStrings.

Value parameters

lhs

The left-hand side ByteString.

rhs

The right-hand side ByteString.

shouldPad

Indicates whether to truncate the result to the length of the shorter input, or to pad with the remaining values from the longer one.

Attributes

Returns

The result of the bitwise AND operation.

See also

CIP-122. Performs a logical bitwise AND operation on each byte between two ByteStrings sequentially and returns the result(Formally result[i] = lhs[i] & rhs[i]). The argument shouldPad determines what to do in the case when ByteStrings are of different lengths. If shouldPad is false, the result will be the length of the shorter input. Otherwise, the result will be padded with the remaining values from the longer input.

Example

andByteString(false, hex"0FFF", hex"FF") == hex"0F"

andByteString(true, hex"0FFF", hex"FF") == hex"0FFF"
