bevy_db

Overview

Async key-value persistence with one Bevy-facing API and two backends:

• Native — redb pure-Rust B+tree on disk
• WASM — rexie over IndexedDB in the browser

All I/O runs off the game thread via bevy_tasker. Game systems poll DbRequest<T> handles via try_recv() to drain results without stalling the schedule.

Surface

• BevyDbPlugin — initializes the backend and inserts the Db resource
• Db — request handle for get / put / delete
• DbRequest<T> — pending async result polled with try_recv()
• DbError — backend-agnostic error enum
