/**
|
|
* A simple, asynchronous, persistent, key-value storage system designed as a
|
|
* backend to the AsyncStorage JS module, which is modeled after LocalStorage.
|
|
*
|
|
* Current implementation stores small values in serialized dictionary and
|
|
* larger values in separate files. Since we use a serial file queue
|
|
* `RKFileQueue`, reading/writing from multiple threads should be perceived as
|
|
* being atomic, unless someone bypasses the `RCTAsyncLocalStorage` API.
|
|
*
|
|
* Keys and values must always be strings or an error is returned.
