Question 1

How does Rouille compare to Actix-web?

Accepted Answer

Rouille uses a synchronous, thread-per-request model ideal for direct control, while Actix-web is async and actor-based for better scalability. Rouille is simpler for learning or small projects, but Actix-web excels in high-concurrency environments.

Question 2

Is Rouille good for building REST APIs?

Accepted Answer

Yes, Rouille's linear request handling and built-in HTTP support make it suitable for REST APIs. However, you'll need to manually implement routing and serialization, as it lacks built-in REST-specific features like some other frameworks.

Question 3

How to handle authentication in Rouille?

Accepted Answer

Since Rouille has no middleware, handle authentication manually in the request handler by checking cookies or headers. Integrate with third-party auth libraries if needed, but expect to write more boilerplate code compared to middleware-based frameworks.

Question 4

Can I use async code with Rouille?

Accepted Answer

Rouille is fundamentally synchronous, but you can spawn async tasks within handlers. The framework doesn't support async I/O natively, so it's not optimized for async workflows, and performance gains may be limited.

Question 5

What are Rouille's performance benchmarks?

Accepted Answer

Rouille achieves about 22k requests/sec for a hello-world, comparable to Node.js but slower than async Rust frameworks like tokio-minihttp at 77k requests/sec. It offers reasonable performance for a synchronous server, as detailed in the FAQ.

Question 6

How to integrate a database with Rouille?

Accepted Answer

Initialize your database connection outside the request handler and use it within, as Rouille is designed for easy integration with any Rust library. There's no framework-specific glue code required, but you must manage connections manually.
