How to use Diesel ORM

Use Diesel by adding it to your Cargo.toml, defining your database schema, and running the diesel CLI to generate types.

[dependencies]
diesel = { version = "2.2.10", features = ["sqlite", "r2d2"] }
libsqlite3-sys = { version = "0.30", features = ["bundled"] }

[dev-dependencies]
diesel_migrations = "2.2.10"

Run cargo install diesel_cli --no-default-features --features sqlite to install the CLI, then diesel setup to create the database and migrations folder. Define your schema in src/schema.rs using diesel::table! macros, and use diesel::prelude::* in your code to query data.

Diesel is a tool that helps Rust programs talk to databases safely and without writing raw SQL. It automatically creates code that matches your database structure, preventing errors before you even run your program. Think of it as a translator that ensures your Rust code and your database always understand each other perfectly.
