Rust for CPython Progress Update April 2026 | Python Insider Rust for CPython project status update April 2026

Just posted the Rust for CPython Progress Update for April 2026 to the Python Insider Blog!

This covers what we've been up to and our roadmap to a PEP. If you're interested in contributing please join our Discord!

2. I don't mind if people don't want to use Rust but instead of rewriting it from scratch every single time, why don't you write bindings and make them available for everyone? This is both easier and more maintainable, and would actually be helpful for the community.

Why pylock.toml includes digital attestations A Python project got hacked where malicious releases were directly uploaded to PyPI. I said on Mastodon that had the project used trusted publishing with digital attestations, then people using a pylo...

I said digital attestations and `pylock.toml` would have helped with the litellm attack. People asked for more details, so I wrote a blog post explaining why it would have helped.

Limit candidate packages to those that were uploaded prior to the given date. Accepts RFC 3339 timestamps (e.g., 2006-12-02T02:07:43Z), local dates in the same format (e.g., 2006-12-02) resolved based on your system's configured time zone, a "friendly" duration (e.g., 24 hours, 1 week, 30 days), or an ISO 8601 duration (e.g., PT24H, P7D, P30D). Durations do not respect semantics of the local time zone and are always resolved to a fixed number of seconds assuming that a day is 24 hours (e.g., DST transitions are ignored). Calendar units such as months and years are not allowed. May also be set with the UV_EXCLUDE_NEWER environment variable.

In light of the fallout from the LiteLLM supply chain attack, I just learned that you can exclude newly published package versions when installing with uv using exclude-newer.

JSSE is a new JS engine made by Claude over two months with four hours human supervision by @p.ocmatos.com

🦀 Choosing Rust aided the feedback loop
💯 Fully-compliant with test262(!)
🐌 Pure interpreter, unoptimized, slow
➰ Longest dev loop: 16 hours on Temporal
💸 ~$4k on Opus 4.6 API calls

Meet JSSE - a Claude Code built Javascript Engine - that passes 100% of the test262 suite. First of a kind... More info at p.ocmatos.com/blog/jsse-a-... #claude #javascript #engine #agents

We are excited to announce that we can successfully use Rust's std::thread on the GPU. This has never been done before.

Supporting Rust's std::thread enables existing Rust code to work on the GPU and makes GPU programming more ergonomic.

NumPy in rust now exists folks. Let the science people know.

i built an entire x86 CPU emulator in CSS (no javascript)

you can write programs in C, compile them to x86 machine code with GCC, and run them inside CSS

What do LLMs see?

I wrote a lil' tool that extracts the attention matrices out of open models and creates this typing visual, with each token's opacity changing according to its average attention score as the prompt progresses. Dimmer words are considered less important to the model.

"you can just use embedded rust libraries off the shelf for GPUs because it's just a normal no-std library, duh" is SUCH a huge validation for how we've structured the embedded Rust ecosystem.

No OS to port, no complex tooling to set up. If you can run rust code, you can just drop no_std crates in.

we live in the ruins of a greater civilization

Mr. C++

Usually in this last situation it would require a few iterations of agent review, human review, simplification, etc.

Also, there are probably many teams out there where the "review pipeline" is already almost a bottleneck, even without LLM agents.

Oh, I mean, it's debatable more in the sense that it really depends on the situation and context.

Maybe the agent will help fix a super hidden bug with changes in 3 lines of code (trivial review), maybe it will generate tons of boilerplate with complex interactions that would require a long review.

"We choose to go to the fucking Moon in this fucking decade and do the other fucking things, not because they are fucking easy, but because they are fucking hard."

Another argument for up:
- This fact will create more demand for Rust, thus for Rust developers

Now, both arguments for down are debatable. AI only helps learning if the developer really really wants to learn, the "easy mode" it creates is to not learn much and just depend on the AI tools.

Rust has a linear algebra problem.

See, linear algebra is super important for many of the applications where Rust is most commonly used. Yet, we have an underwhelming set of linear algebra libraries.
