Safe C++ proposal is not being continued

news.ycombinator.com Unknown 2025-10-01 12:00:29

One year ago, the Safe C++ proposal was made. The goal was to add a safe subset/context into C++ that would give strong guarantees (memory safety, type safety, thread safety) similar to what Rust provides, without breaking existing C++ code. It was an extension or superset of C++. The opt-in mechanism was to explicitly mark parts of the code that belong to the safe context. The authors even state: Code in the safe context exhibits the same strong safety guarantees as code written in Rust. The

Active phishing campaign targeting crates.io users

We received multiple reports of a phishing campaign targeting crates.io users (from the rustfoundation.dev domain name), mentioning a compromise of our infrastructure and asking users to authenticate to limit damage to their crates. These emails are malicious and come from a domain name not controlled by the Rust Foundation (nor the Rust Project), seemingly with the purpose of stealing your GitHub credentials.

The repercussions of a typo in C++ & Rust

The repercussions of missing an Ampersand in C++ & Rust Copying vs Passing by reference TL;DR There’s a funny typo that causes someone to copy data instead of “referencing” in C++. Rust is nice because it provides defaults that protect you from some of these “dumb” mistakes. In this example, I’ll go over how the “move by default” can prevent us from introducing this subtle behavior.

I never knew how to order things. The flip side was that usually when you understand all the basic components in play lots of it just fits together. i.e. there's some point where the interwovenness turns from a barrier into something incredibly valuable and helpful. —Jana Dönszelmann Visio
