Inspect Cennznut Fields

Getter functions for inspecting a CENNZnut

const cennznut = new Cennznut(...);
  module = cennznut.getModule("module_test"); // returns the module with name 'module_test' if exist else returns undefined
  contracts =  cennznut.getContract(contract_address); // returns contract with contract_address if exist else returns undefined

Cennznut Encoding and Decoding

Encoding: Encode a cennznut object

Decoding: Create a cennznut object from a encoded cennznut

const Cennznut = require('@cennznet/cennznut-wasm').default;

const payload = [0, 0, 0, 1, 109, 111, 100, 117, 108, 101, 95, 116, 101, 115, 116, ..., 0, 0, 0, 0, 0, 0, 0, 0, 0];
const cennznut = Cennznut.decode(payload);

const cennznut = new Cennznut(...);
const encoded = cennznut.encode();
