promisify

import { promisify } from "https://raw.githubusercontent.com/takker99/async-lib/0.1.0/mod.ts";

callbackをPromiseに変換するやつ

function promisify<T, E = unknown>(options?: PromisifyOptions): readonly [() => Promise<T>, (value: T) => void, (reason: E) => void];

promisify<T, E = unknown>(options?: PromisifyOptions): readonly [() => Promise<T>, (value: T) => void, (reason: E) => void]

E = unknown

options?: PromisifyOptions optional

readonly [() => Promise<T>, (value: T) => void, (reason: E) => void]

左から順に、Promiseを返すやつ、正常値を受け取るcallback、異常値を受け取るcallback
