Cargo features

Choose features on the Git dependency. For SQLite with Rustls and Axum:

alibi = { version = "0.1.1", default-features = false, features = ["axum", "sqlx-sqlite", "rustls"] }

Feature	Default	Enables
axum	no	Axum: AxumIntegration, CurrentSession, OptionalSession
poem	no	Poem: PoemIntegration, session extractors
sqlx	yes	SQLx store for SQLite and PostgreSQL (sqlx-sqlite + sqlx-postgres)
sqlx-sqlite	via sqlx	SQLx with SQLite only
sqlx-postgres	via sqlx	SQLx with PostgreSQL only
seaorm	no	SeaORM store
redis-cache	no	RedisAdapter for secondary storage and shared rate limits
native-tls	yes	OpenSSL for outbound HTTP (OAuth, email verification, CAPTCHA, …) and the SQLx/SeaORM PostgreSQL drivers
rustls	no	Rustls instead of OpenSSL

Rules of thumb

• Pick exactly one TLS feature. The default is native-tls; to use rustls, disable default features.
• Pick the engine you use. Disabling default features and selecting sqlx-sqlite or sqlx-postgres removes the other engine’s code. SqlxPool::connect returns a configuration error for a URL whose engine is not compiled in.
• Frameworks are opt-in. Without axum or poem, use BetterAuth::handle_request directly (Other frameworks).
• SeaORM and SQLx are independent. Enable one or both; each provides its own store, hooks and rate-limit storage.

Common combinations

# PostgreSQL + Axum + Rustls (typical production)
alibi = { version = "0.1.1", default-features = false, features = ["axum", "sqlx-postgres", "rustls"] }

# SeaORM + Poem + Rustls
alibi = { version = "0.1.1", default-features = false, features = ["poem", "seaorm", "rustls"] }

# Axum + SQLx + Redis-backed sessions and rate limits
alibi = { version = "0.1.1", features = ["axum", "redis-cache"] }

Your own sqlx dependency must enable the same engine ("sqlite" and/or "postgres") plus chrono, json and derive, because the generated models derive sqlx::FromRow.
