Async #Rust is actually awesome!

The last few days I've built a prototype(!) of a global "Hotkey" system e.g.:

Press & Hold LCtrl + Space
=> an async stream starts and only finishes if:
- another key is pressed or
- one of the Hotkeys is released

If it is not clear by now: this is a state-machine, which fits perfectly into Rust's #async model!

And the best part: This is actually the first time I've ever touched async #RustLang! Such a pleasant experience!

#AsyncRust

Cross-compiling a #Rust project that has custom build scripts that build C/C++ dependencies is an absolute clusterfuck!

I'm trying to cross-compile a Rust project from #Linux -> #Windows (x86_64-pc-windows-gnu) and I get walls of errors!

Some I could already fix by setting env vars to different compilers (gcc, g++, oh my!), but now I'm stuck. Maybe some missing compiler flags to gcc?

Or could it be related to this?

Second: Pinning helpers!

When doing async #Rust, there will be a point, where you'll get the ominous "Doesn't implement Unpin" error and "You need to pin your value".

First, learn about Pinning:
https://doc.rust-lang.org/std/pin/

Like, really learn and understand it:
https://fasterthanli.me/articles/pin-and-suffering

And then use smol's pin! macro and the pin_project crate:
https://docs.rs/pin-project/latest/pin_project/

I might continue this thread with more insights I gain during this little project - stay tuned! 🙂

I'm stuck trying to decide whether to implement my own hash table, or use an additional and unnecessary level of pointers with unordered_map

C++17 gave us std::vector, std::list and std::forward_list of incomplete types (HOW DID IT TAKE THAT LONG), but from what I can tell, not even C++26 will have std::unordered_map of incomplete types :(

Of course in #Rust, vectors and hash maps and everything else just works with recursive types no problem

#cplusplus#cpp

I work at @system76 as Principal Engineer where I maintain our Linux distribution @pop_os_official, port @coreboot and open source embedded controller firmware to our laptops, work on the new desktop environment @COSMIC_desktop, and more!

I also am the creator and BDFL of a microkernel operating system primarily written in @rust called @redox. I am damn near crazy about #Rust and use it anywhere and everywhere!

Turns out, I know just enough Rust to implement Brainfuck interpreter. I don't get to use profanities in code often, I took the opportunity.

Heck yeah, this thing will blow up!

Introducing Operese (a Windows-to-Linux migration tool made by a nerd):

https://yewtu.be/watch?v=PMoXClh8emw
(or YT: https://www.youtube.com/watch?v=PMoXClh8emw)

The demo is very impressive! 👀

It apparently migrates your #Windows10 installation to #Linux #Kubuntu (❤️) with all your files ready to use. 🚀

Written in #Rust, but not yet #OpenSource (according to author will be Open Source in the near future).
