A tour of the Axum web framework for Rust (while explaining a few error messages)

Skip to 02:05 to go straight to the code.

Axum, a sub-project of Tokio that works together with sibling crates tower, tonic and hyper, promises ergonomics and modularity. Is that fair? This video introduces viewer to some of the introductory concepts of Axum including response types and its extractor system.

Yes! Watching this when I get home. More Axum!

another video on tracing please, badly needed.

Great video, love to see more like this

I always thought the promise is "If it compiles, it runs". Seeing the extractor error at 13:00 is a real bummer

Axum is great, ive combined it with rpc, works great 👍

Regarding the cryptic error messages, there is a handy little helper in the form of the axum::debug_handler macro which can help there. Not sure about the particular case discussed in the video. Great content!

Thank you! - Please could you do part 2 and show how we could add Swagger UI maybe?! 👍

[jimii_]

thanks for this. Would love for you to do a comparison of axum to actix web.

quite a nice framework, ive used warp in the past but am going to make a simple api with axum next

If I remember correctly, tokio is utilising tower to build services that are stackable. It already had some helper functions to quickly make services. My hunch is that make_service thing is related to that. There is probably a trait somewhere in tokio, that can be implemented to make your handler into a service in tower, that is stackable. Hence "into make service", which will then has blanker implementation of "into service".

hello guys. I’m a Rust programmer. Does anyone want to hire?

This honestly looks like a terrible development experience
