Sequence 568 v393

About This Type

Variable-length list of u32 values.

A dynamically-sized collection. The encoded length precedes the element data.

Encoding: Compact<u32> length prefix followed by each element encoded in sequence.

Examples

3-element Vec<u32> = [elem0, elem1, elem2]
0x0c<elem0><elem1><elem2>
0c Compact length = 3
<elem0>... Each u32 encoded in sequence

Code Examples

import { TypeRegistry } from "@polkadot/types";

const registry = new TypeRegistry();

// Encode a Vec<u32>
const vec = registry.createType("Vec<u32>", [1, 2, 3]);
console.log("Hex:", vec.toHex());
