/**

* @beta

|

|
|
*
|
||
|
|
* Attaches `Symbol.asyncDispose` methods to the MongoClient, Cursors, sessions and change streams
|
||
|
|
* if Symbol.asyncDispose is defined.
|
||
|
|
*
|
||
|
|
* It's usually not necessary to call this method - the driver attempts to attach these methods
|
||
|
|
* itself when its loaded. However, sometimes the driver may be loaded before `Symbol.asyncDispose`
|
||
|
|
* is defined, in which case it is necessary to call this method directly. This can happen if the
|
||
|
|
* application is polyfilling `Symbol.asyncDispose`.
|
||
|
|
*
|
||
|
|
* Example:
|
||
|
|
*
|
||
|
|
* ```typescript
|
||
|
|
* import { configureExplicitResourceManagement, MongoClient } from 'mongodb/lib/beta';
|
||
|
|
*
|
||
|
|
* Symbol.asyncDispose ??= Symbol('dispose');
|
||
|
|
* load();
|
||
|
|
*
|
||
|
|
* await using client = new MongoClient(...);
|
||
|
|
* ```
