In this chapter, we took a quick look at a few ways to perform basic database interaction using Rust by using the low-level SQLite and PostgreSQL library crates. We saw how to augment database connectivity with a connection pool using r2d2. Finally, we made a small application with Diesel, a safe and performant ORM.
In the next chapter, we'll take a look at how Rust can be made to run on the web by using a bleeding edge technology called WebAssembly.
