/**
|

* @name promisify
|
||||
* @summary Wraps an async callback into a `Promise`
|
||||
* @description
|
||||
* Wraps the supplied async function `fn` that has a standard JS callback `(error: Error, result: any)` into a `Promise`, passing the supplied parameters. When `error` is set, the Promise is rejected, else the Promise resolves with the `result` value.
|
||||
* @example
|
||||
* <BR>
|
||||
*
|
||||
* ```javascript
|
||||
* const { promisify } from '@pezkuwi/util';
|
||||
*
|
||||
* await promisify(null, ((a, cb) => cb(null, a), true); // resolves with `true`
|
||||
* await promisify(null, (cb) => cb(new Error('error!'))); // rejects with `error!`
|
||||
* ```
|
||||

function promisify(self, fn, ...params) {
|
||||
return new Promise((resolve, reject) => {
|
||||
fn.apply(self, params.concat((error, result) => {
|
||||
if (error) {
|
||||
reject(error);
|
||||
}
|

else {
|
||||
resolve(result);
