RustCon все ближе, а у нас на сайте все больше согласованных докладов. Сегодня знакомим вас с Егором Ивковым из Qdrant и его докладом «New and upcoming Rust language features»

Доклад будет особенно полезен, если у вас уже есть опыт в работе Rust и желание узнать, в какую сторону язык будет развиваться дальше. Егор обещает разобрать свежие семантические и синтаксические изменения в языке Rust (например, Const Generics и Generic Associated Types). Потом вместе обсудим, где и для чего их можно использовать, сравним, как они соотносятся с дизайном других известных языков.

А еще посмотрим на широко обсуждаемые сейчас Generic Keywords и Context и поговорим про такую острую тему как Higher Kinded Types и нужны ли они расту.

В этом году RustCon пройдет в онлайн и офлайн-форматах. Посмотреть другие доклады программы и купить билет по ранней цене можно на сайте.

Rust 1.65.0 released!🥳

Main features
- Generic Associated Types
- let ... else ... statements

With GATs getting into Rust and all that, what do you think about Higher-Kinded Types? Should they be introduced into Rust?

The one I've been waiting here for is definitely hint::black_box that recommends to compiler to disable optimisations in a particular place.

Had a few actual cases for this, when the code which is meaningful is optimised away.

# Rust 1.66.0

Highlights:

- Explicit discriminants on enums with fields
- core::hint::black_box
- cargo remove
- ..=X ranges in patterns

Killer feature

You don't need to debug if there are no bugs. Any valid Rust syntax is guaranteed to be bug free and do exactly what you intend for it to do. The people that still debug are the ones who haven't figured out that smashing your face on the keyboard and pushing straight to production is perfectly valid in the Rust context.

This is what I feel has happened to the Rust core and other teams. Passionate people - who were originally there - burned out and are slowly being replaced by community members that just care for prestige.

Support for Rust is being added to the Chromium project, so that contributors could use Rust libraries from their C++ source.

Scala Resurrection by John A De Goes

Critical problems in Scala:
- Scala 3 is still rather academic, should focus more on being production ready
- Scala 3 is not backwards compatible (Interesting to note this negative reaction to Scala 3 in context of recent Rust 2.0 proposals. I also think that any Rust 2.0 should just be a different language)
- Still poor IDE and build tools support
- Still only focused on JVM
- Difficult and opinionated community in a rather unopinionated language

# The Old Ways

A bit of nostalgia: how #RustLang package management looked like back in 2014 before Cargo got released? In my hobbyist experience, it usually was a mix of make, cmake, and messy shell noscripts :D

Nothing personal🤷‍♂
