Vec<Compact<u64>>

Sequence 149 v393

About This Type

Variable-length list of Compact<u64> values.

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

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

Sequence (Vec)

Element Type: Compact<u64>
SCALE Encoding: Length-prefixed (Compact<u32> length followed by elements)

SCALE Encoding

Rule: Compact<u32> length prefix followed by each Compact<u64> element encoded in sequence.
Size: variable

Examples

3-element Vec<Compact<u64>> = [elem0, elem1, elem2]

0x0c<elem0><elem1><elem2>

0c Compact length = 3

<elem0>... Each Compact<u64> encoded in sequence

Code Examples

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

const registry = new TypeRegistry();

// Encode a Vec<Compact<u64>>
const vec = registry.createType("Vec<Compact<u64>>", [1, 2, 3]);
console.log("Hex:", vec.toHex());
