Rust news # 4 (December 2018)

Since the holidays are over, I offer you a subjective selection of rusty news for December. In this compilation: madness with growth, whether growth is terrible, a wave of prophecies, Rust 2018, Rust Analyzer.

Rust 1.31 & Rust 2018

The most important event of December is the release of Rust 1.31 and Rust 2018 , of course. There are a lot of things included:

edition 2018, non-lexical lifetimes, changes to the module system, additional rules for lifetimes output, const fn, new tools, instrumental code quality checks, documentation, new website, improvements in cargo.

There are so many changes that the review of all could not be crammed into one post, so after a few days supporting notes were published:

• Procedural Macros in Rust 2018 ( discussion ) - on procedural macros;
• Tools in the 2018 edition ( discussion ) - on expanding the toolkit;

Also, it makes sense to look through a Mozilovsky well-structured review / educational program of the 2018th edition of the language: Rust 2018 is here ... but what is it? ( translation , discussion ).

A wave of posts about plans for 2019

An official request was sent to the community to share views on the 2019th year - A call for Rust 2019 Roadmap blog posts ( discussion ). In response, a wave of more than a hundred articles followed (all can be found at readrust.net/rust-2019 ). Here are some interesting answers:

• Boatman: "Rust 2019: Organizational Debt" ( discussion );
• Graydon: "Rust 2019 and beyond: limits to (some) growth" ( discussion , translation );
• Klabnik: "Thoughts on Rust in 2019" ( discussion );
• Ralph: "My thoughts on Rust 2019" ( translation );

RustRush 2018

December 15-16, Moscow hosted RustRush 2018 .

Records will be gradually published on the Youtube channel , while two are available:

• Keynote. Ashley Williams - about community spirit and wasm-bindgen;
• Libp2p, a Rust peer-to-peer library. Pierre Krieger ;

Also, Pierre Chevalier posted a trip report .

Generation of type objects on the fly (or madness with Rust)

idubrov wrote an interesting article on low-level hacks with fierce unsafe. An excellent experiment for learning purposes, but I hope it will not go into real projects.

Is it so scary Rust, as he is painted

PsyHaSTe fights the perception of rust exclusively as a system language.

Rust Analyzer in 2018 and 2019

Lesha matklad shared information on the progress of the rust-analyzer project , which is an alternative to RLS ( discussion ).
An important thing, considering that IDE is a very painful topic for Rasta.
