:core:datastore

Overview

The :core:datastore module manages structured, asynchronous data storage using Jetpack DataStore. It is primarily used for storing complex configuration objects like radio channel sets and local device configurations.

Key Components

1. Data Sources

• ChannelSetDataSource: Manages the storage of radio channel configurations.
• RecentAddressesDataSource: Stores a list of recently connected radio addresses (BLE/USB/TCP).
• UiPreferencesDataSource: Modern replacement for SharedPreferences for UI-related settings.

2. Serializers

Uses Kotlin Serialization to convert between Protobuf/JSON and the underlying DataStore storage.
