Jon Gjengset explores the internals of the axum web framework, explaining tower services, handlers, and state extractors.

In this stream, we peel back the crust on the axum crate — github.com/tokio-rs/axum/ — and explore its interface, structure, and mechanisms. We talk about tower::Service, the Handler trait, Routers, and the State extractor. We also get into the way axum ensures at compile time that all handlers have access to the state that they'll need at runtime. For more details about axum, see docs.rs/axum/latest/axum/.

What people say. Highly recommended for understanding how Axum works at a deep level, especially its complex generic handler system.

On “Super heavy generic on HTTP lib makes debugging hard”

I agree that these special extractor traits can feel a bit like "magic" and be a bit confusing. But it's pretty common for web frameworks to try to have this kind of API. I still think what Axum does is more understandable than what java does.with spring boot. Jon Gjengset has a nice video explaining Axum which cleared things up for me. link to this video

On “How does an Axum handler work at the language level?”

This video is long, but it does a great job at explaining it: link to this video I made the link point to the time code where he starts talking about your question for about 45 minutes.

On “How to go from Zero to Rust backend developer?”

For understanding the basics I found Jon Gjengset very interesting and informative, for some fun projects you can try code-crafters.

If you wanna come to learn how the Axum crate works at a deep level, I highly recommend watching this video by Jon Gjengset. Two hours long, but great stuff from a very credentialed rust educator in the scene.
