Yes, I would like to see more videos on macros. They are a very powerful tool

[tserica]

Probably worth mentioning that its a good idea to write complex procedural macros with proc_macro2, because that allows the logic to be used outside of your macros, and allows for creating tests that are difficult to write otherwise.

[evidgamer]

This series should be the official rust video tutorial. Very precise, concise and clear.

Phew!!! That's a lot of stuff but the best explanation about the different types of macros so far... to be honest, I didn't know what to search for to get information about a term like "#[route(GET, "/")] because I didn't know how it is called 🤦‍♀ You videos a always a good starting point and most of the stuff is absolutely clear then... Thanks!!

[nko]

F***Ing amazing! Best explanation for macros I've ever found! It had been complicated to find a clear explanation about this and it has been very helpful. Lots of thanks for your work! 🙌

[bonkbonk]

Excellent video! I think it would be nice a video exploring different examples and problems that implement macros, specially attribute like macros and function like macros.

[cj]

This really helped me understand derive macros, thanks so much!

[KayOScode]

Ok these are unbelievably powerful. I thought the macro system would be worse than a language like c because theyre trying to make it safer. I definitely didnt expect to be able to define my own language inside them

[uowemegrand]

2:24 "We'll discuss why we'll need to bring two crates into scope in just a second"

Was this ever explained? Sorry if I had missed it.

[cappedvillain]

It's a little complicated... Can you spend some time elaborating with possible examples

[netify]

Rust macros are powerful and neat from consumer perspective, on the other hand some of them makes code flow less obvious and code inspection harder.

[allaboutworld]

Great series I had ever seen please add some more Projects too that would be more helpful thanks

[voidwalker]

procedural macros for the gainzzz, buraaahh !!!

[arjentix]

Hello, I came from C++, and don't understand some things. Is using macros a good choice in Rust code? Are there some disadvantages? Should I first try to implement macro using basic macros, and only if that failed I should try to use procedural macros?

[in_action]

How do I write a procedural macro which supports struct both with and without lifetime annotations?

[workflowinmind]

How do you bring HelloMacro into scope 6:29? Should the derive crate have the macro on as dep?

[subhamprasad]

macros are hard to understand... honestly i still confuse and lost

[arimcbrown]

How much time does it cost for you to produce 1 video every time? (preparation included)

[rootkill]

Hey Bogdan! I think you're doing really great by making these videos for the rustaceans! But I do have a query about the std::io.. can you make a video about the inputs in rust.. to take different types inputs like int, long long, float, double etc.. It will be really great if this topic will be covered.. - New rustacean (rustling maybe)

[pineiden]

Nice, macros we're some obscure to me yet and i Will be thansfull if You can show more abour
