SQLx

nidus-sqlx provides official SQLx adapter primitives for pool registration, optional config loading, health checks, and observability hooks.

nidus-sqlx = { version = "1.0.4", features = ["sqlite", "nidus-config", "health", "observability"] }

Use sqlite or postgres to select the SQLx backend. Add nidus-config when pool settings should come from Nidus config, health when readiness should validate database connectivity, and observability when adapter-owned operations should emit framework observability.

Nidus does not own your schema migrations, query design, ORM layer, or transaction policy. Those stay in SQLx and application code.
