Bytes32Type Bytes32 to check

Returns

boolean True if all bytes are zero

Example

if (Bytes32.isZero(b32)) {
  console.log("Empty slot");
}

max()

max(a, b): Bytes32Type

Defined in: src/primitives/Bytes32/max.js:15 Return the maximum of two Bytes32 values (lexicographically)

Parameters

a

Bytes32Type First Bytes32

b

Bytes32Type Second Bytes32

Returns

Bytes32Type The larger value

Example

const larger = Bytes32.max(a, b);

min()

min(a, b): Bytes32Type

Defined in: src/primitives/Bytes32/min.js:15 Return the minimum of two Bytes32 values (lexicographically)

Parameters

a

Bytes32Type First Bytes32

b

Bytes32Type Second Bytes32

Returns

Bytes32Type The smaller value

Example

const smaller = Bytes32.min(a, b);

toBigint(bytes32): bigint

Defined in: src/primitives/Bytes32/toBigint.js:12 Convert Bytes32 to bigint (big-endian)

Parameters

bytes32

Bytes32Type Bytes32 to convert

Returns

bigint Big-endian bigint representation

Example

const value = Bytes32.toBigint(b32);

toHex()

const value = Bytes32.toNumber(b32);

zero()

zero(): Bytes32Type

Defined in: src/primitives/Bytes32/zero.js:13 Create a zero-filled Bytes32

Returns

Bytes32Type New Bytes32 with all zeros

Example

const empty = Bytes32.zero();
