"Zero To Production In Rust" is complete 🦀 It is a start-to-finish guide for building APIs using @rustlang. A mix of pragmatic advice and foundational concepts. @zero2prod is the book I wished I had when I started. Two years in the making - it feels surreal to be *done*.

Mainmatter is looking for an experienced Rust developer to join one of our projects as a freelancer. We're migrating a database from C to Rust. The project is complex and performance-sensitive. That's what makes it fun! If you're interested, send an email to the address in the

I'll be a busy bee! I'll kick off on November 2nd with a Rust-Python interoperability workshop. On November 4th I'll be @fasterthanlime's sparing partner in his unfair Rust quiz and I'll close down the conference schedule with a talk on dependency injection. Looking forward 🚀

Less than 10 days left before Rustlab! It's a conference that's close to my heart—one of the first I spoke at, back in 2019! Years have been passed, but the vibe and the community have only improved. Tickets are still available—use `SP20FR` for a last-minute 20% discount.

Days since I needed Span::join on stable: 0

RustConf just uploaded on YouTube the recording of my C-to-Rust migration talk! Check it out if you want to learn more about the Rust work we've been doing on Redis Query Engine over the past few months. https://t.co/tzfTsvS9ey

Concrete goal: define a driver-agnostic way to configure a Postgres connection. Then you research the details, obsess over an aspect (i.e. SSL configuration) and end up working for several ways on a generic way to configure a TLS client policy. Cool, but slow.

Only two weeks to go!

Looking forward to @rustconf and @OxidizeConf, where I'll get a chance to dive into the details of the thought process and technical strategy that made this possible.

New Redis release, but with a twist. It includes our first Rust patches to Redis Query Engine! In particular, it ships the new TrieMap implementation I wrote with @hdoordt, as part of @mainmatter's ongoing collaboration with Redis.

The integration into their Academy plugin is pretty slick! A nice way to get started with Rust without leaving the IDE.

If you're in a position to hire a compiler developer, rush it! Giving @compiler_errors the opportunity to continue working on Rust is probably the most impactful contribution that your company can make to the project.

That beautiful feeling of being ~done on a 35k lines* PR 🍉 *Don't do this at work. **Many lines are test snapshot updates.

We have another opening at Mainmatter, this time for a *technical writer*. You'd be working directly with me on new Rust training material, blog posts and other kinds of technical long-form content. If you're interested, send your resume job AT mainmatter DOT com

An even better solution: you can set an MSRV *just for clippy* via clippy.toml. This will configure a variety of lints to behave as if you were using that version to run clippy, including the collapsible_if one. Back to fearless toolchain updates!

If you want to mitigate the problem, slap `#![allow(clippy::collapsible_if)]` on your crate.

Rust 1.89.0 will stabilize let-chains (yay 🎉). In the same release, clippy will flag `if` statements that can be collapsed further using a let-chain. Outcome: your CI will fail when 1.89.0 is released, and you can't fix it ahead of time because the feature clippy wants you to

It's official now: I'll be a speaker at RustConf 2025 🎉 My talk falls into the "Interop & Migration" theme, covering the work we've been doing with Redis, supporting the migration of some of their C code to Rust. You'll get all the details when the full schedule is announced!

Two things can be true at the same time: - You can achieve ~everything with enough practice - Dan Luu is spot on when he says that "95%-ile isn't that good" If you've never read the article, this is your chance:
