markup.rs VS actix-web

(Sailfish is fastest, but it's syntax is of the more traditional <%= msg %> flavour and Markup.rs is second-fastest with a Maud-like syntax but the author apparently doesn't have time to rewrite the syntax reference, so you have to follow a link from the open issue to an old version of the README.)

Maud or markup.rs for templating (I use the latter, and it is faster, but they're both fast and markup.rs is currently missing its full syntax documentation unless you dig through the revision history for the stale version. I'd recommend the former for you.)

For the sake of thoroughness, I should point out that Haml-like templating engines like Maud and markup.rs are even more concise.

https://maud.lambda.xyz/ or https://github.com/utkarshkukreti/markup.rs for server-side HTML templates that compile to Rust code

(eg. In Python, Genshi templates are too slow for me to feel comfortable using them, but they were the main way to get robust correctness checks for templates last time I evaluated my options. In Rust, Markup.rs or Maud are the second and third fastest templating solutions, as I remember, and they give even more well-formedness guarantees for HTML than Genshi.)

There are various templating solutions that use syntax derived from the host language, like Maud or markup.rs for Rust, the E factory API for lxml for Python, etc.

You can have similar features to Phoenix Live View by using Turbo from Hotwire with your favorite template engine in Rust. Contrary to what the video presentation on the Hotwire main page leaves you to believe, Hotwire works with any template engine from any language, not just Rails. Markup.rs and Turbo from Hotwire should compose quite nicely.

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.
