This is a guest post from the gccrs project, at the invitation of the Rust Project, to clarify the relationship with the Rust Project and the opportunities for collaboration. gccrs is a work-in-progress alternative compiler for Rust being developed as part of the GCC project. GCC is a collection of compilers for various programming languages that all share a common compilation framework. You may h

The default way impl Trait works in return position is changing in Rust 2024. These changes are meant to simplify impl Trait to better match what people want most of the time. We're also adding a flexible syntax that gives you full control when you need it. TL;DR Starting in Rust 2024, we are changing the rules for when a generic parameter can be used in the hidden type of a return-position impl T

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 co

Rust has long had an inconsistency with C regarding the alignment of 128-bit integers on the x86-32 and x86-64 architectures. This problem has recently been resolved, but the fix comes with some effects that are worth being aware of. As a user, you most likely do not need to worry about these changes unless you are: Assuming the alignment of i128/u128 rather than using align_of Ignoring the improp

As shown above, in 2023, we have received 37% fewer survey views in vs 2022, but saw a slight uptick in starts and completions. There are many reasons why this could have been the case, but it’s possible that because we released the 2022 analysis blog so late last year, the survey was fresh in many Rustaceans’ minds. This might have prompted fewer people to feel the need to open the most recent su

Announcing `async fn` and return-position `impl Trait` in traits The Rust Async Working Group is excited to announce major progress towards our goal of enabling the use of async fn in traits. Rust 1.75, which hits stable next week, will include support for both -> impl Trait notation and async fn in traits. This is a big milestone, and we know many users will be itching to try these out in their o

The Rust compiler's front-end can now use parallel execution to significantly reduce compile times. To try it, run the nightly compiler with the -Z threads=8 option. This feature is currently experimental, and we aim to ship it in the stable compiler in 2024. Keep reading to learn why a parallel front-end is needed and how it works, or just skip ahead to the How to use it section. Compile times an

Around mid-October of 2023 the crates.io team was notified by one of our users that a shields.io badge for their crate stopped working. The issue reporter was kind enough to already debug the problem and figured out that the API request that shields.io sends to crates.io was most likely the problem. Here is a quote from the original issue: This crate makes heavy use of feature flags which bloat th

Generators are dead, long live coroutines, generators are back We have renamed the unstable Generator trait to Coroutine and adjusted all terminology accordingly. If you want to see all 3800 modified lines of code, you can find the PR here. Our Generator trait was effectively a coroutine already, so this change was long overdue. All nightly users using the Generator trait must now update their cod

May 29, 2023 · leadership chat membership on behalf of leadership chat On May 26th 2023, JeanHeyd Meneide announced they would not speak at RustConf 2023 anymore. They were invited to give a keynote at the conference, only to be told two weeks later the keynote would be demoted to a normal talk, due to a decision made within the Rust project leadership. That decision was not right, and first off w

Introduction About 9 months ago we announced the creation of the Keyword Generics Initiative; a group working under the lang team with the intent to solve the function coloring problem 1 through the type system not just for async, but for const and all current and future function modifier keywords as well. We're happy to share that we've made a lot of progress over these last several months, and w

Oh hey, it's another new team announcement. But I will admit: if you follow the RFCs repository, the Rust zulip, or were particularly observant on the GATs stabilization announcement post, then this might not be a surprise for you. In fact, this "new" team was officially established at the end of May last year. There are a few reasons why we're sharing this post now (as opposed to months before or
