Learning Rust: Procedural Macros

This is part 2 of an ongoing series of my efforts to learn the programming language Rust. I give you a quick overview on how to create a simple procedural macro.
The final code can be found here:

From someone who was trying to get his head around quote, syn, and procedural macros for the first time, this was super helpful. Thank you! I have subscribed- keep the great content coming.

Wow, this is the exact problem I try to tackle for a long time! It will jumpstart my progress. Subbed!

You don't need to make a closure right 'filter_map(|field| get_entity_field(field))'? should work?

This is exactly what I've been looking for. Great videos. You never miss. Thanks so much.

Great video! I am less scared to touch them now :)
One question: I always assumed that the derive macro is used to autogenerate trait implementations. Here you inject the select directly into the Book struct implementation block. Is this common procedure, or just to keep it simple for a start?

fantastic video, excellent explanations and editing. Because you obviously are a great coder I am thinking that you must have a pretty streamlined video editing process, and you picked your tools carefully. Could you share more about those? I need to put myself out there and learn by sharing videos, but the editing part is what bothers me most. How can you deliver such clean videos? Right now the only tools I have are obs studio and blender

Thanks for the video! Is there any reason you used the match statement instead of the `?` operator?

[adsick_ua]

If I understand correctly, there is no need to match field.ident in get_entity_field function as we've already matched fields to be named, so simply .unwrapping that Option will be fine.

I’m still to wrap my head around all the things he blew by the explanation

Nice tutorial on the topic but the inlay hint is quite messy and is distracting.

[pinch-of-salt]

I love your fish/vim setup. Make a full tutorial on that? rustlang is the best! Hope it has this niche and small fanbase forever instead of becoming mainstream.

[hirisraharjo]

Nice tutorial. But please turn off the music completely next time because your explanations are more important than the music

Als du deinen Namen gesagt hast war ich mir zu 100% sicher ich hätte auf ein deutsches Video geklickt. Ich war richtig schockiert als du auf einmal englisch geredet hast.
