Definition
----------
.. phpmethod:: MongoDB\\InsertOneResult::getInsertedId()
Return the ID (i.e. ``_id`` field value) for the inserted document.
.. code-block:: php
function getInsertedId(): mixed
Since IDs are created by the driver, this method may be called irrespective
of whether the write was acknowledged.
Return Values
-------------
The ID (i.e. ``_id`` field value) of the inserted document.
If the document had an ID prior to inserting (i.e. the driver did not need to
generate an ID), this will contain its ``_id`` field value. Any driver-generated
ID will be a :php:`MongoDB\\BSON\\ObjectId <class.mongodb-bson-objectid>`
instance.
