onStop
Invoked when Store.close is invoked.
This is called after the store is already closed, and you cannot influence the outcome.
This is invoked for both exceptional stops and normal stops.
Will not be invoked when an Error is thrown.
Warning:
This function is called in an undefined coroutine context on a random thread, when the pipeline is already canceled. It should be fast and non-blocking.
Parameters
e
the exception the store is closed with. Can be null for normal completions. For everything except kotlinx.coroutines.CancellationExceptions, will not be null.
