Said the inner block inside the for loop could not be a function, because break does not mean anything not inside a loop, but the macro, which seems like a function, injects it into the code which is inside a loop, which is valid

That's really cool, I was not familiar with this and will look into it!

Thanks!

Couldn't agree more, both on proc macros and operating system, I did not find sufficient information on the internet. That is exactly the purpose of this book.

Yea that's sound about right

The macro explained in that section was mainly for me to learn macros, and save up some boilerplate with nice syntax.

Thanks for the warming comment!

During the development of Learnix operating system I needed to represent bitflags inside some structures.

While there were alternatives with 3rd party libraries, the goal of the project is to implement and learn as much as I can.

Most of the guides I found online explained the concept great, but created only a simple macro as an example. So I decided to write about it myself too, with a real usage to create a bitfields attribute proc-macro, that takes a struct and turns it into bitfields.

Hope you will have a great read!

Hi! This is a project that I am working on for quite a while.

The main goal is to teach operating systems and Rust.

This is still 'beta' and a lot of things are missing (especially Rust chapters) but I would like to know what you think if it :)

I plan to cover more, like disk drivers, file systems, processes, shell, user space, processes, until we can run a working program!

Hopefully, also networking

This project started because I wanted to understand the linux that sits on my computer, which is x86. There is a possibility that on the future it will have multiple architectures supported, probably starting with arm, but I can't promise that

You are correct, and it will be fixed!

Because I didn't really publish it, I didn't check all the grammar and type errors

This is something I will improve when the initial release will come

That's actually an interesting idea, the main reason is that I wanted to take a doom port that is posix compliant and see if I can make it run
