auths-storage

Storage adapters for the identity and registry ports defined in auths-id.

Role

This crate contains adapters only — no domain logic. It implements the port traits from auths-id::ports (e.g., RegistryBackend, AttestationSource) for specific storage backends. The identity domain in auths-id never imports from this crate.

auths-storage  ──depends on──▶  auths-id::ports
auths-id       (never imports from auths-storage)
binary crates  ──depend on──▶  both

Feature Flags

No features are enabled by default. Binary crates select the backend they need.

Wiring a Backend (Composition Root)

use std::sync::Arc;
use auths_id::ports::RegistryBackend;
use auths_storage::git::GitRegistryBackend;

// In main.rs or app startup — the only place that knows the concrete type.
let backend: Arc<dyn RegistryBackend + Send + Sync> =
    Arc::new(GitRegistryBackend::new(config));

// Inject into application state — all downstream code sees only the trait.
let state = AppState { registry: backend };

Adding a New Backend

1. Create src/<backend>/mod.rs and src/<backend>/adapter.rs
2. Implement RegistryBackend from auths_id::ports::registry
3. Add a feature flag in Cargo.toml
4. Export from src/lib.rs behind #[cfg(feature = "backend-<name>")]
