proc-macro-workshop VS actix-web

Tangentially, the proc macro workshop walks through building a derive macro implementing a builder pattern. From experience, I can tell I couldn't ever write proc macros just by reading the manual, going through it is really helpful https://github.com/dtolnay/proc-macro-workshop/blob/master/README.md

I am working on the proc macro workshop and am a little stuck on the builder portion of the workshop. Step 08-unrecognized-attributes wants you to handle the car where the field modifier has a misspelled portion (eac instead of each)

I would very much second the suggestion to do David Tolnay’s Proc Macro Workshop if you want to start understanding how to write them. I’d been writing Rust for years but always kind of avoided proc macros.

When I had a need for them, I went through only the first section of the workshop and everything clicked. You can just do the derive macro section and all the strange and scary-looking macro syntax will make sense. I realized that there is only a bit of extra syntax but it’s used very often so it can seem a little overwhelming when reading macro code.

Another good one imo is the proc-macro-workshop.

Don't be afraid of proc macros and derive macros, they rule. Study the basic examples. Crates like darling and resources like David Tolnay's workshop will help. Write derives for your simpler traits and impress your colleagues.

Regarding 4, I think that macros are an interesting intermediate/advanced topic. I personally loved the material from https://github.com/dtolnay/proc-macro-workshop

It took me a while to get anything done. My mistake : I came accross the procedural macros workshop several times, and every time I dismissed it, thinking - meh I'll just hack together exactly what I need and move on. Then finally I figured there is no way around it. The builder exercise sounds boring but it covers the topic pretty well. And then I went on to the debug one and from there was able to build the proc macro I wanted.

Actix Web Documentation: Detailed documentation on using Actix-web, including examples and best practices for building web applications with Rust.

I can't speak to the "is it any good" part, but (after a bit of research) I can share what I've found. I'll try to represent things as best as I understand, but I may have some finer details mixed up.

ntex is written by the same person that started actix-web, Nikolay Kim (fafhrd91 on GitHub). There was a bunch of drama a while back due to actix-web using (what many reasoned to be) avoidable unsafe code, which was later found to be buggy. Nikolay was pilloried online, resulting in him transferring leadership of actix-web to someone else. ntex is, as I understand it, essentially Nikolay picking back up on his ideals for what could have been actix-web, if people hadn't pushed him out of his own project.

How ntex compares to the pre-/post-leadership change of actix-web, I don't know.

Here are some jumping points if you want more of the backstory.

Are you ready to embark on another journey in Rust? Today, we'll explore how to create a REST API that performs basic mathematical operations: addition, multiplication, and division. We'll use Actix, a powerful web framework for Rust, together with Rhai, a lightweight scripting language, to achieve our goal.

Within actix-web, middleware is used as a medium for being able to add general functionality to a (set of) route(s) by taking the request before the handler function runs, carrying out some operations, running the actual handler function itself and then the middleware does additional processing (if required). By default, actix-web has several default middlewares that we can use, including logging, path normalisation, access external services and modifying application state (through the ServiceRequest type).

Rust is a popular system programming language, known for its robust memory safety features and exceptional performance. While Rust was originally a system programming language, its application has evolved. Now you can see Rust in different app platforms, mobile apps, and of course, in web apps — both in the frontend and backend, with frameworks like Rocket, Axum, and Actix making it even easier to build web applications with Rust.
