Using Rust Code in a C/C++ Project with CMake by Sebastien Duquette
I am currently working on Wayk Now written in C for the most part. We recently started writing new code for it in Rust which I’m super excited about.

As we needed a way to integrate this code in our CMake build1, we wrote a set of modules for CMake
Extreme benchmark feedback using Gitlab CI by Ruben De Smet
I am quite notorious for exploiting Gitlab’s CI. Ever since I started playing with it at the start of 2016, I tended to make things worse.
C2Rust Demonstration by Galois and Immunant
The C2Rust project is being developed by Galois and Immunant. This tool is able to translate most C modules into semantically equivalent Rust code. These modules are intended to be compiled in isolation in order to produce compatible object files. We are developing several tools that help transform the initial Rust sources into idiomatic Rust.
My Emacs Rust IDE by Bill Ward
In this post, I will walk you through configuring an EMACS Rust IDE to get syntax highlighting and code completion for the Rust programming language.
What do you think are the most interesting/exciting projects using Rust? by Nick Cameron
Last week I tweeted "What do you think are the most interesting/exciting projects using Rust? (No self-promotion :-) )". The response was awesome! Jonathan Turner suggested I write up the responses as a blog post, and here we are.
To do a Rust GUI by Jos van den Oever
Rust Qt Binding Generator lets you combine Rust code with a Qt1 graphical application. A previous blog shows how to make a simple clock. It’s a good idea to read that post before reading this more advanced post, because in this post we are getting serious.

This blog post shows how to write a to-do application. The data model is a list of to-do items. The source code for this example is available in the folder examples/todos in the Rust Qt Binding Generator repository.
Fishing in an Abyss: Building a Password Cracker in Rust by Sam Schlinkert
Ahead of this year’s World Password Day, 1Password – maker of password management software – announced a password cracking challenge. The company ostensibly wanted to find out how hard it would be to crack a three-word passphrase master password on one of their vaults, assuming that the attacker had the derived hash of the passphrase.
madparts-rs 1.0 release by Joost Yervante Damad
Back in Februari 2013 then coworker Romain S. showed me the new trend of programming editors that do continuous compilation while you type, showing you immediate feedback on your code. In parallel I also worked on 3D modeling for my 3D printer using the OpenSCAD program. OpenSCAD works by writing code in its custom language and then have it rendered. I had this idea of combining these two approaches to make an electronics footprint generator. And so the development of the original madparts program started. In August 2016 I had been playing with the then pretty new rust programming language and decided a rewrite in it and simplifying the program even further would be fun to do.
An image viewer using Smithay's Client Toolkit by Victor Berger
Small tutorial of using Smithay's Client Toolkit by example, building a small image viewer as a Wayland client.
Analyze disk usage with dutree by nachoparker
dutree is a command line tool to analyze disk usage. Features coloured output, according to the LS_COLORS environment variable, display the file system tree, ability to aggregate small files, ability to exclude files or directories, ability to compare different directories fast, and written in Rust. This tool is a mix between tree and durep.
Entity-Component-System architecture for UI in Rust by Raph Levien
For a fun project, I’ve been tinkering with xi-win, an experimental Windows front-end for xi-editor, written in Rust. I’m basically optimizing for performance, so making a number of somewhat unusual decisions. Among other things, I’m writing the UI myself, rather than using an existing toolkit or framework.
sudo_pair - Plugin for sudo that requires another human to approve and monitor privileged sudo sessions by Square
sudo is used by engineers daily to run commands as privileged users. But on some sensitive systems, you really want to ensure that no individual can act entirely autonomously. At Square, this includes applications that manage our internal access-control systems, store accounting ledgers, or even move around real money. This plugin allows us to ensure that no user can act entirely on their own authority within these systems.
My Compound Passphrase List Safety Checker by Sam Schlinkert
I’ve been thinking about information theory, entropy, and passphrases for a couple of months now. I’ve been particularly interested in using random passphrases as passwords. An example of one of these passphrases would be “stamina turret backlands ruby”. The words have to be as purely random as possible – using your four dogs’ names is not nearly as strong as a password, as an attacker would likely guess that relatively early.
Filtering Duplicate Log Entries via Rust and Runiq by Isaac Whitfield
Whilst sort -u is super easy to use, the requirement of sorting your data cannot be overlooked as it means your entire file needs to be buffered into memory at once. This is not always possible, or even if possible it's not always desired. On the other hand uniq is great, but in order to sort your data in advance you still have the same issue. It was due to this that I wrote runiq, which is essentially an optimized and more flexible implementation of both of the aforemention tools for the purposes of duplicate filtering. It performs much faster, with much less memory, and does not require sorted input (although it can optimize this case).
Introducing seiri — a music 🎶 manager for lots of music by Ronny Chan
TL;DR seiri is a lightweight music manager written (mostly) in Rust that helps keep huge music libraries organized. Try it today at
kanban-app - Kanban board built with Rust and Elm without Electron by Huy Tr.
This is a web-based Kanban board application, built with Elm and Rust. The only different from this application and hundred thousands of web-based application out there is: We don't need Electron!. Instead, it use native WebView (WebKit for Linux/macOS, and MSHTML on Windows),
Servo engines written in Rust deliver memory safety and multithreading by Mozilla Research
In 2012, Mozilla started the Servo project, a community effort to create new open source browser components that can take advantage of multicore hardware to improve speed, stability and responsiveness. Servo is comparable to WebKit, an open source browser engine that is the foundation of Apple’s Safari browser. (Other browser engines include Blink, EdgeHTML, and Gecko.) The difference is that Servo is written in the Rust programming language, bringing lightning-fast performance and memory safety to browser internals. Rust code can drastically cut down the number of critical bugs that affect browser engines. Servo uses a modular architecture and currently runs on Linux, macOS, Windows, and Android operating systems.
bat - print code to the terminal with syntax highlighting and git integration by David Peter
bat supports syntax highlighting for a large number of programming and markup languages. bat also communicates with git to show modifications with respect to the index (see left side bar).
JARVIS - Notes on Rust Crates From Writing an RSS Reader by Brook Heisler
Way back in the dim mists of history (back in university) I wrote myself a custom RSS reader in Java and called it JARVIS1. You see, I read a lot of webcomics. Like, a lot. Some webcomics provide RSS feeds, but some don’t, and as my collection grew it started to become a hassle to use Firefox’s live bookmarks to manage it all. Ultimately, I wrote up a quick Swing GUI to use as a single interface for keeping up with blogs and tracking which comics had published updates since the last time I’d checked2.
Hammond: A Podcast Client for the GNOME Desktop by Jordan Petridis
Hammond has been in development since Sep 2017. It makes use of the Rust bindings to GNOME libraries as well as diesel, serde, reqwest, and a number other crates to build a beautiful, native application that feels right at home on the GNOME desktop.
fastmod - A fast partial replacement for the codemod tool by Facebook Incubator
fastmod is a fast partial replacement for codemod. Like codemod, it is a tool to assist you with large-scale codebase refactors, and it supports most of codemod's options. fastmod's major philosophical difference from codemod is that it is focused on improving the use case "I want to use interactive mode to make sure my regex is correct, and then I want to apply the regex everywhere". For this use case, it offers much better performance than codemod
Pijul 0.10 by Pijul
I’m pleased to announce the new release of Pijul, version 0.10. Pijul is an easy to use, distributed and fast version control system. This release has been a long time coming, but brings in an important number of new features and stability enhancements.
Announcing cargo src (beta) by Nick Cameron
cargo src is a new tool for exploring your Rust code. It is a cargo plugin which runs locally and lets you navigate your project in a web browser. It has syntax highlighting, jump to definition, type on hover, semantic search, find uses, find impls, and more.
dust - A more intuitive version of du in Rust by andy boot
Dust is meant to give you an instant overview of which directories are using disk space without requiring sort or head. Dust will print a maximum of 1 'Did not have permissions message'. Dust will list the 15 biggest sub directories or files and will smartly recurse down the tree to find the larger ones. There is no need for a '-d' flag or a '-h' flag. The largest sub directory will have its size shown in red
angle-grinder - Slice and dice log files on the command line by Russell Cohen
Angle-grinder allows you to parse, aggregate, sum, average, percentile, and sort your data. You can see it, live-updating, in your terminal. Angle grinder is designed for when, for whatever reason, you don't have your data in graphite/honeycomb/kibana/sumologic/splunk/etc. but still want to be able to do sophisticated analytics.

Angle grinder can process about a million rows per second, so it's usable for fairly meaty aggregation. The results will live update in your terminal as data is processed. Angle grinder is a bare bones functional programming language coupled with a pretty terminal UI.
Faster Bulletproofs with Ristretto & AVX2 by Chain
A few months ago, Bünz, Bootle, Boneh, Poelstra, Wuille, and Maxwell published Bulletproofs, which dramatically improves proof performance both in terms of proof size and verification time. In addition, it allows proving a much wider class of statements than just range proofs.

At Chain, we (Henry de Valence, Cathie Yun and Oleg Andreev) have been working on a pure-Rust Bulletproofs implementation, whose initial version we are publishing today, together with a set of notes.
QCGPU - Hardware Accelerated Quantum Computer Simulation by QCGPU

New sysinfo version (huge performance improvements!) by Guillaume Gomez
This new version comes with great performance improvements. We're talking about 3x faster on macos, 2x faster on linux and 3x faster on windows (the benchmarks are at the end of the post).
Sequoia-PGP - a modular OpenPGP implementation by p≡p foundation
Sequoia is a modular OpenPGP implementation in Rust.
Announcing personal finance tool 'pfr' by Antony Southworth
pfr is a command-line tool for helping me to manage my personal finances. At the end of each month, I like to sit down and “allocate” funds to cover my expenses for the following month. However, not all of my expenses occur monthly. For example, things like rent are paid weekly, and I think of money spent on food in terms of weeks, so I have to multiply those expenses by 4 (ish). I also have to figure out how much money to put in each account, e.g on my EFTPOS (direct-debit) card or for automatic payments. It’s not hard, but then again, that’s why we write programs.
Introducing Click: The Command Line Interactive Controller for Kubernetes by Nick Lanham
Click is an open-source tool that lets you quickly and easily run commands against Kubernetes resources, without copy/pasting all the time, and that easily integrates into your existing command line workflows. This blog introduces its its usage and merits.
From to gutenberg by Christoph Grabo (@asaaki)
I wish I could have the features of both tools, but for now I will use gutenberg over cobalt. A tiny migration and feature comparison story.

Compiling Rust + Windows + GTK step-by-step by light3rn
In case you have tried to make a rust program with GUI that would work both on Linux and Windows, you probably may have faced some issues in some point (especially if you are a newcomer). Compiling in Linux is quite easy, but in Windows life gets a bit tricky.

I've pulled together some info from here and there so that no-one else had to fight their way through fire and flames.
Presentation Manager written in Rust by Mario García
A tool for serving and managing presentation slides.
Building a fast Electron app with Rust by Kevin J. Lynagh
When I built Finda, I wanted it to be fast — specifically, to respond to all user input within 16 milliseconds.

Given this goal, you might be surprised to learn that Finda is built with Electron, a framework that’s often decried for being the opposite of fast.
A Tiny `ls` Clone Written in Rust by Matthias Endler
In my series of useless Unix tools rewritten in Rust, today I'm going to be covering one of my all-time favorites: ls.
Oxidizing Fedora: Try Rust and its applications today by Igor Gnatenko and Neal Gompa
In recent years, it has become increasingly important to develop software that minimizes security vulnerabilities. Memory management bugs are a common cause of these vulnerabilities. To that end, the Mozilla community has spent the last several years building the Rust language and ecosystem which focuses primarily on eliminating those bugs. And Rust is available in Fedora today, along with a few applications in Fedora 27 and higher, as seen below.
How to write GStreamer Elements in Rust Part 2: A raw audio sine wave source by Sebastian Dröge
A bit later than anticipated, this is now part two of the blog post series about writing GStreamer elements in Rust. Part one can be found here, and I’ll assume that everything written there is known already. In this part, a raw audio sine wave source element is going to be written. It will be similar to the one Mathieu was writing in his blog post about writing such a GStreamer element in Python. Various details will be different though, but more about that later.
Snips Uses Rust to Build an Embedded Voice Assistant by Judy DeMocker
The team at Paris-based Snips has created a voice assistant that can be embedded in a single device or used in a home network to control lights, thermostat, music, and more. You can build a home hub on a Raspberry Pi and ask it for a weather report, to play your favorite song, or to brew up a double espresso. Manufacturers like Keecker are adding Snips’ technology to products like multimedia home robots. And Snips works closely with leaders across the value chain, like NVIDIA, EBV, and Analog Devices, in order to voice-enable an increasingly wider range of device types, from speakers to home automation systems to cars.
Spectra gets Rust scripting! by Dimitri Sabadie
spectra is a crate I’ve been maintaining for a few months / years now. It’s a crate that I mainly use for demoscene productions (I released two with it, Céleri Rémoulade and Outline Invitation) but I also use it to play around and experiment new rendering, animation and video game techniques.
Fanta: An opinionated framework for web development in rust by Peter Mertz
Fanta is a web framework that aims for developers to be productive and consistent across projects and teams. Its goals are to be: Opinionated, Fast, and Intuitive. Based heavily off of the work here:
comm is a peer-to-peer instant messaging protocol designed to be resilient to censorship by Zac Stewart
comm is a peer-to-peer instant messaging protocol designed to be resilient to censorship. comm-gtk is a GUI client built on the comm library. To try it out, start the app. In the configuration window, enter a secret phrase, a bootstrap node (IP:port pair), and a local port to listen on (e.g. 6669). For a bootstrap node, try (or any other node's IP address if you know one). Click connect to join the network.
tealdeer - A very fast implementation of tldr in Rust. by Danilo Bargen
A fast command line client for tldr: A collection of simplified and community-driven man pages.
Reflecting on ppbert by Vincent Foley
I had an itch: I was pretty-printing the BERT-encoded terms that we use in a production system at work and it was very slow. The Erlang shell took more than two minutes to dump the largest file. (It took about 0.1 second to read and parse the file; the rest was spent in io:format.) I decided to scratch that itch: I wrote ppbert, a command-line utility that reads BERT-encoded values and pretty-prints them. I’ve worked sporadically on ppbert for almost a year now, I use it daily at work, I’m happy with it, and I want to write about some of the things I learned during that journey.
Guitar Effects in Rust by Ricky Han
In an effort to experiment with dsp, I wrote a guitar/bass effects processor this past weekend. The end result works very well (to my pleasant surprise). It doesn’t have 90% of the functionalities of any of rakarrack, guitar rig, garage band but overall it was a fun weekend hack.
DataFusion: Big Data Platform for Rust by Andy Grove
DataFusion is an open-source Big Data platform implemented in the Rust programming language with a similar programming style to Apache Spark.
retrobasic - A BASIC interpreter written in Rust by seasalim

Writing a command-line program in Rust - Federico's Blog by Federico Mena Quintero
As a library writer, it feels a bit strange, but refreshing, to write a program that actually has a main() function. My experience with Rust so far has been threefold:
Make your own make by Aleksey Kladov
An obvious idea is to use Rust for task automation. Originally, I have proposed creating a special Cargo subcommand to execute build tasks, implemented as Rust programs, in this thread. However, since then I realized that there are built-in tools in Cargo which allow one to get a pretty ergonomic solution. Namely, the combination of workspaces, aliases and ability to define binaries seems to do the trick.
