Another new lang from Google - https://github.com/carbon-language/carbon-lang

It is quite strange to include inheritance in a modern language. Though they want it to be "a direct successor to C++", so I guess their ideas are rather rooted in C++ design and style of thinking.

# Serde Tips

A nice /r/rust thread with tips about using serde_json, some of which are not so obvious. I only got two things to add:

- Don't forget to read through serde.rs, it covers most of the day-to-day knowledge. It's surprising how many serde users don't know about it.

- Consider using lib.rs/nanoserde if you only need some basic features and care about the size of your project's dependencies.

Generic associated types in Rust are going to be stabilized soon - https://twitter.com/AliceICecile/status/1565110186456539136?t=MkhLkmKqKXK08esNrXxGOw&s=19

This is a big change for the Rust type system

Graydon is the original creator of Rust and he now works on Swift.

GATs stabilization is merged👀 As far as I understand, we should expect to be able to use it in 1.65 release in stable rust!

wasmtime reaches 1.0 release! It is a personal favorite of mine among the WebAssembly runtimes and I think it should be a big step in WASM adoption

An updated mdbook about Rust macros - https://github.com/Veykril/tlborm

I remember using the original one (2016 edition) when studying them, it's cool that Rust team is finally continuing this effort

Iterator semantics for Future and Stream - https://docs.rs/futures-concurrency/latest/futures_concurrency/

For now it's a separate crate, but it is a part of the work done currently by async working group. So we can expect it to be merged into std soon.

This year I will be participating in RustCon as a speaker with a couple of topics I was closely tracking in the past several months. So don't hesitate to join the conference online or offline😊. The video recordings will probably be available after a 6 month delay.

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
