9//! # apalis-sql
10//! apalis offers Sqlite, Mysql and Postgres storages for its workers.
11//! See relevant modules for examples
12//!
13//! **Features**
14//!
15//! These features can be used to enable SQLx functionalities:
16//! - `mysql` - MySQL support.
17//! - `postgres` - PostgreSQL support.
18//! - `sqlite` - SQLite support.
19//! - `migrate` - Migrations for Apalis tables.
20//! - `async-std-comp` - Use [async-std](https://async.rs/) runtime and [rustls](https://docs.rs/rustls/latest/rustls/).
21//! - `async-std-comp-native-tls` - Use [async-std](https://async.rs/) runtime and [native-tls](https://docs.rs/native-tls/latest/native_tls/).
22//! - `tokio-comp` - Use [Tokio](https://tokio.rs/) runtime and [rustls](https://docs.rs/rustls/latest/rustls/).
23//! - `tokio-comp-native-tls` - Use [Tokio](https://tokio.rs/) runtime and [native-tls](https://docs.rs/native-tls/latest/native_tls/).
24//!
25//! For more information about the runtime and TLS features, see the [SQLx features documentation](https://docs.rs/sqlx/latest/sqlx/).
