Module matrix_sdk_base::store

The state store holds the overall state for rooms, users and their profiles and their timelines. It is an overall cache for faster access and convenience- accessible through Store.

Implementing the StateStore trait, you can plug any storage backend into the store for the actual storage. By default this brings an in-memory store.
