It has been more than a year since the initial blog post announcing the Types team, and our initial set of goals. For details on what the team is, why it was formed, or our previously-stated overarching goals, go check out that blog post. In short the Types team's purview extends to the parts of the Rust language and compiler that involve the type system, e.g. type checking, trait solving, and borrow checking. Our short and long term goals effectively work to make the type system sound, consistent, extensible, and fast. Before getting into details, it's worth sharing a quick point: the team ov ..read more

TL;DR: rustc will use rust-lld by default on x86_64-unknown-linux-gnu on nightly to significantly reduce linking times. Some context Linking time is often a big part of compilation time. When rustc needs to build a binary or a shared library, it will usually call the default linker installed on the system to do that (this can be changed on the command-line or by the target for which the code is compiled). The linkers do an important job, with concerns about stability, backwards-compatibility and so on. For these and other reasons, on the most popular operating systems they usually are older pr ..read more

Similar to our previous announcements of the Rust Project's participation in Google Summer of Code (GSoC), we are now announcing our participation in Open Source Promotion Plan (OSPP) 2024. OSPP is a program organized in large part by The Institute of Software Chinese Academy of Sciences. Its goal is to encourage college students to participate in developing and maintaining open source software. The Rust Project is already registered and has a number of projects available for mentorship: C codegen backend for rustc Extend annotate-snippets with features required by rustc Improve bootstrap Mod ..read more

The Rustup team is happy to announce the release of Rustup version 1.27.1. Rustup is the recommended tool to install Rust, a programming language that is empowering everyone to build reliable and efficient software. If you have a previous version of Rustup installed, getting Rustup 1.27.1 is as easy as stopping any programs which may be using Rustup (e.g. closing your IDE) and running: $ rustup self update Rustup will also automatically update itself at the end of a normal toolchain update: $ rustup update If you don't have it already, you can get Rustup from the appropriate page on our we ..read more

The Cargo and Compiler team are delighted to announce that starting with Rust 1.80 (or nightly-2024-05-05) every reachable #[cfg] will be automatically checked that they match the expected config names and values. This can help with verifying that the crate is correctly handling conditional compilation for different target platforms or features. It ensures that the cfg settings are consistent between what is intended and what is used, helping to catch potential bugs or errors early in the development process. This addresses a common pitfall for new and advanced users. This is another step to o ..read more

The Rust Project is participating in Google Summer of Code (GSoC) 2024, a global program organized by Google which is designed to bring new contributors to the world of open-source. In February, we published a list of GSoC project ideas, and started discussing these projects with potential GSoC applicants on our Zulip. We were pleasantly surprised by the amount of people that wanted to participate in these projects and that led to many fruitful discussions with members of various Rust teams. Some of them even immediately began contributing to various repositories of the Rust Project, even befo ..read more
