Haxl.Core.RequestStore

Bucketing requests by DataSource.

When a request is issued by the client via dataFetch, it is placed in the RequestStore. When we are ready to fetch the current batch of requests, the contents operation extracts the fetches, bucketed by DataSource.

This module is provided for access to Haxl internals only; most users should not need to import it.
