Database & Async Runtime

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

Cargo.toml

sea-orm = { version = "^0", 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-actix-native-tls, runtime-async-std-native-tls, runtime-tokio-native-tls, runtime-actix-rustls, runtime-async-std-rustls, runtime-tokio-rustls

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

• ASYNC_RUNTIME can be actix, 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
actix	Actix
async-std	Tide
tokio	Axum, Rocket, Poem

2. native-tls uses the platform's native security facilities, while rustls is a pure Rust implementation.

Extra features

debug-print - print every SQL statement to logger

mock - mock interface for unit testing
