Building fewer targets by default On 2026-05-01, docs.rs will make a breaking change to its build behavior. Today, if a crate does not define a targets list in its docs.rs metadata, docs.rs builds documentation for a default list of five targets. Starting on 2026-05-01, docs.rs will instead build do...

Rust's WebAssembly targets are soon going to experience a change which has a risk of breaking existing projects, and this post is intended to notify users of this upcoming change, explain what it is, and how to handle it. Specifically, all WebAssembly targets in Rust have been linked using the --all...

The Rust team has published a new point release of Rust, 1.94.1. Rust is a programming language that is empowering everyone to build reliable and efficient software.

The Rust Security Response Team was notified of a vulnerability in the third-party crate tar, used by Cargo to extract packages during a build. The vulnerability, tracked as CVE-2026-33056, allows a malicious crate to change the permissions on arbitrary directories on the filesystem when Cargo extra...

When we set out to understand Rust's challenges, we expected to hear about the borrow checker learning curve and maybe some ecosystem gaps. Of course, we did. A lot. But, of course, it's more nuanced. The conventional wisdom is that Rust has a steep learning curve, but once you "get it," smooth sail...

We would welcome people to try and report issues with the nightly-only cargo -Zbuild-dir-new-layout. While the layout of the build dir is internal-only, many projects need to rely on the unspecified details due to missing features within Cargo. While we've performed a crater run, that won't cover ev...

We're launching a Rust Debugging Survey. Various issues with debugging Rust code are often mentioned as one of the biggest challenges that annoy Rust developers. While it is definitely possible to debug Rust code today, there are situations where it does not work well enough, and the quality of debu...

We are happy to announce that the Rust Project will again be participating in Google Summer of Code (GSoC) 2026, same as in the previous two years. If you're not eligible or interested in participating in GSoC, then most of this post likely isn't relevant to you; if you are, this should contain some...

The crates.io team will no longer publish a blog post each time a malicious crate is detected or reported. In the vast majority of cases to date, these notifications have involved crates that have no evidence of real world usage, and we feel that publishing these blog posts is generating noise, rath...
