Database & Async Runtime

We need your support! ⭐

Thank you for using SeaORM. Please star our GitHub repo! Your support is vital to the continued development and maintenance of SeaORM.

First, add sea-orm to the [dependencies] section of Cargo.toml.

Cargo.toml

sea-orm = { version = "0.12", features = [ <DATABASE_DRIVER>, <ASYNC_RUNTIME>, "macros" ] }

You must choose a DATABASE_DRIVER and an ASYNC_RUNTIME. macros is needed if you use SeaORM's generated entities (most likely).

DATABASE_DRIVER

You can choose one or more from:

• sqlx-mysql - SQLx MySQL and MariaDB
• sqlx-postgres - SQLx PostgreSQL
• sqlx-sqlite - SQLx SQLite

See also: SQLx docs.

ASYNC_RUNTIME

You have to choose one from:

runtime-async-std-native-tls, runtime-tokio-native-tls, runtime-async-std-rustls, runtime-tokio-rustls

Basically, they are in the form of runtime-ASYNC_RUNTIME-TLS_LIB:

• ASYNC_RUNTIME can be async-std or tokio
• TLS_LIB can either be native-tls or rustls

1. Choose the ASYNC_RUNTIME corresponding to your Rust web framework:

ASYNC_RUNTIME	Web Framework
async-std	Tide
tokio	Axum, Actix, Poem, Rocket

2. native-tls uses the platform's native security facilities, while rustls is an (almost) pure Rust implementation.
