If you're wondering I took three days off and spent a whole weekend on my slides.

(Also the subject is way more complex this time)

[S🦀sha @scrabsha]

Now I think I can say it

The slides of my eurorust 2022 talk were ready 20h before giving the talk. I did exactly 0 rehearsals before giving it for real.

It went well, but it was still a horrible idea. Next time I'll take a couple of days off.

Wait until you discover how a macro expansion is proved

@CohenArthurDev If you need help type `sizeof void` two times

[S🦀sha @scrabsha]

@zdimension_ @DrawsMiguel Thanks. I hate it

[EuroRust @euro_rust]

Start your afternoon with @scrabsha on proving macro expansion, followed by Lukas Wirth @Veykril on powerful macros and IDE support. Wrap up with @ENYBjoern on C++ APIs using Rustdoc and procedural macros. See you there! 👀🌟🦀 #eurorust24

@louispilfold @CohenArthurDev @duolingo We are ashamed by our language quirkiness

@CohenArthurDev rustfmt does precisely this on the following code :D

macro_rules! foo {
($($tt:tt)*)
}

(Happens at least on the latest nightly)

@CohenArthurDev @fasterthanlime I need to understand how it works. I think I need to do a deep dive in merde to find out

[S🦀sha @scrabsha]

@charliermarsh When I started hacking rustc, I was stunned by the amount of dyn. Basically "if it is not perf sensitive or if it is too cumbersome to have a generic type parameter, then go dyn go".

It felt good to see that kind of pragmatic choice *in rustc itself*.

@teoledozo Je suis jalouse.
