/**
 * @name Rpc
 * @summary The API may use a HTTP or WebSockets provider.
 * @description It allows for querying a Polkadot Client Node.
 * WebSockets provider is recommended since HTTP provider only supports basic querying.
 *
 * ```mermaid
 * graph LR;
 *   A[Api] --> |WebSockets| B[WsProvider];
 *   B --> |endpoint| C[ws://127.0.0.1:9944]
 * ```
 *
 * @example
 * <BR>
 *
 * ```javascript
 * import Rpc from '@polkadot/rpc-core';
 * import WsProvider from '@polkadot/rpc-provider/ws';
 *
 * const provider = new WsProvider('ws://127.0.0.1:9944');
 * const rpc = new Rpc(provider);
 * ```
