The new project directory should look like this. In the code above, we set up the project and named it classroom_diesel. Your first step is to initialize the project by running the following command: cargo new - lib classroom_diesel Initializing a new project with Diesel ORM The following steps demonstrate how to set up a Rust project with Cargo that uses Diesel ORM. Having scratched the surface, let’s explore how to interact with relational databases with Diesel and SQLx. When using SQLx, you must craft the SQL queries and migrations yourself. SQLx supports connection pooling, cross-platform development, nested pooling, asynchronous notifications, transport layer security, and other exciting features. It is both database- and runtime-agnostic. SQLx is an asynchronous Rust SQL crate that features compile-time SQL query checks. ORMs also make you less prone to SQL injection attacks. Using ORMs, you can communicate with relational databases as if they are object-oriented.įor less experienced developers, using ORMs might be better because ORMs craft optimized SQL queries. ORMs are shipped with query builders, so you don’t have to worry about writing raw SQL queries. ORMs help object-oriented programmers abstract the details of relational databases. ORM stands for object-relational mapping. What is Diesel?ĭiesel is an ORM that supports PostgreSQL, MySQL, SQLite. To follow along with this tutorial, you will need a working knowledge of Rust along with the ability to access and use Rust, Rust’s build system and package manager Cargo, and a MySQL server instance. Using SQLx and Rust to update or delete database records.Initializing a new project with Diesel ORM.We’ll perform CRUD operations using Diesel ORM and SQLx. This article will use a simple classroom database with students to demonstrate each approach. In this tutorial, we’ll explore two libraries used when interacting with relational databases in Rust: Diesel and SQLx.
