Module backend 

Backend trait bridging sqlitegraph with higher-level graph consumers.

This module contains the core GraphBackend trait and redirects to modular backend implementations. SQLite-specific implementations are in the sqlite submodule.

Traits

AsyncGraphBackend

AsyncGraphBackend defines non-blocking graph operations. Supports async/await natively using Rust 2024 edition features.

GraphBackend

Each trait method delegates to backend-specific primitives while ensuring deterministic behavior and a single integration surface for consumers.
