Class MoveVector<T>

This class is the Aptos Typescript SDK representation of a Move vector<T>, where T represents either a primitive type (bool, u8, u64, ...) or a BCS-serializable struct itself.

It is a BCS-serializable, array-like type that contains an array of values of type T, where T is a class that implements Serializable.

The purpose of this class is to facilitate easy construction of BCS-serializable Move vector<T> types.

Example

// in Move: `vector<u8> [1, 2, 3, 4];`
const vecOfU8s = new MoveVector<U8>([new U8(1), new U8(2), new U8(3), new U8(4)]);
// in Move: `std::bcs::to_bytes(vector<u8> [1, 2, 3, 4]);`
const bcsBytes = vecOfU8s.toUint8Array();

// vector<vector<u8>> [ vector<u8> [1], vector<u8> [1, 2, 3, 4], vector<u8> [5, 6, 7, 8] ];
const vecOfVecs = new MoveVector<MoveVector<U8>>([
  new MoveVector<U8>([new U8(1)]),
  MoveVector.U8([1, 2, 3, 4]),
  MoveVector.U8([5, 6, 7, 8]),
]);

// vector<Option<u8>> [ std::option::some<u8>(1), std::option::some<u8>(2) ];
const vecOfOptionU8s = new MoveVector<MoveOption<U8>>([
   MoveOption.U8(1),
   MoveOption.U8(2),
]);

// vector<MoveString> [ std::string::utf8(b"hello"), std::string::utf8(b"world") ];
const vecOfStrings = new MoveVector([new MoveString("hello"), new MoveString("world")]);
const vecOfStrings2 = MoveVector.MoveString(["hello", "world"]);

Methods

bcsToBytes

bcsToBytes(): Uint8Array
Serializes a Serializable value to its BCS representation. This function is the Typescript SDK equivalent of bcs::to_bytes in Move.

Returns Uint8Array
the BCS representation of the Serializable instance as a byte buffer
Implementation of TransactionArgument.bcsToBytes
Inherited from Serializable.bcsToBytes
- Defined in src/bcs/serializer.ts:27

bcsToHex

bcsToHex(): Hex
Helper function to get a value's BCS-serialized bytes as a Hex instance.

Returns Hex
a Hex instance with the BCS-serialized bytes loaded into its underlying Uint8Array
Implementation of TransactionArgument.bcsToHex
Inherited from Serializable.bcsToHex
- Defined in src/bcs/serializer.ts:37

serialize

serialize(serializer): void
Serialize an argument to BCS-serialized bytes.
Parameters

serializeForEntryFunction

serializeForEntryFunction(serializer): void
Serialize an argument as a type-agnostic, fixed byte sequence. The byte sequence contains the number of the following bytes followed by the BCS-serialized bytes for a typed argument.
Parameters
- serializer: Serializer
Returns void
Implementation of TransactionArgument.serializeForEntryFunction
- Defined in src/bcs/serializable/moveStructs.ts:60

serializeForScriptFunction

serializeForScriptFunction(serializer): void
NOTE: This function will only work when the inner values in the MoveVector are U8s.
Parameters
- serializer: Serializer
Returns void
Implementation of TransactionArgument.serializeForScriptFunction
- Defined in src/bcs/serializable/moveStructs.ts:69

`Static` deserialize

deserialize<T>(deserializer, cls): MoveVector<T>

If you're looking for a more flexible deserialization function, you can use the deserializeVector function in the Deserializer class.

- deserializer: Deserializer
- cls: Deserializable<T>
Returns MoveVector<T>
a MoveVector of the corresponding class T *

```
const vec = MoveVector.deserialize(deserializer, U64);
```
Params
