Looking at Rust if it could be an interesting programming language by jsmeix

Get some basic understanding of Rust security related features from a general point of view.

This Hack Week project is not to learn Rust to become a Rust programmer. This might happen later but it is not the goal of this Hack Week project.

The goal of this Hack Week project is to evaluate if Rust could be an interesting programming language.

An interesting programming language must make it easier to write code that is correct and stays correct when over time others maintain and enhance it than the opposite.

Learn how to use the Relm4 Rust GUI crate by xiaoguang_wang

Relm4 is based on gtk4-rs and compatible with libadwaita. The gtk4-rs crate provides all the tools necessary to develop applications. Building on this foundation, Relm4 makes developing more idiomatic, simpler, and faster.

Learn a bit of embedded programming with Rust in a micro:bit v2 by aplanas

Description

micro:bit is a small single board computer with a ARM Cortex-M4 with the FPU extension, with a very constrain amount of memory and a bunch of sensors and leds.

The board is very well documented, with schematics and code for all the features available, so is an excellent platform for learning embedded programming.

Rust is a system programming language that can generate ARM code, and has crates (libraries) to access the micro:bit hardware. There is plenty documentation about how to make small programs that will run in the micro:bit.

Goals

Start learning about embedded programming in Rust, and maybe make some code to the small KS4036F Robot car from keyestudio.

Resources

• micro:bit
• KS4036F
• microbit technical documentation
• schematic
• impl Rust for micro:bit
• Rust Embedded MB2 Discovery Book
• nRF-HAL
• nRF Microbit-v2 BSP (blocking)
• knurling-rs
• C++ microbit codal
• microbit-bsp for Embassy
• Embassy

Diary

Day 1

• Start reading https://mb2.implrust.com/abstraction-layers.html
• Prepare the dev environment (cross compiler, probe-rs)
• Flash first code in the board (blinky led)
• Checking differences between BSP and HAL
• Compile and install a more complex example, with stack protection
• Reading about the simplicity of xtask, as alias for workspace execution
• Reading the CPP code of the official micro:bit libraries. They have a font!

Day 2

• There are multiple BSP for the microbit. One is using async code for non-blocking operations
• Download and study a bit the API for microbit-v2, the nRF official crate
• Take a look of the KS4036F programming, seems that the communication is multiplexed via I2C
• The motor speed can be selected via PWM (pulse with modulation): power it longer (high frequency), and it will increase the speed
• Scrolling some text
• Debug by printing! defmt is a crate that can be used with probe-rs to emit logs
• Start reading input from the board: buttons
• The logo can be touched and detected as a floating point value

Day 3

• A bit confused how to read the float value from a pin

Exploring Rust's potential: from basics to security by sferracci

Description

This project aims to conduct a focused investigation and practical application of the Rust programming language, with a specific emphasis on its security model. A key component will be identifying and understanding the most common vulnerabilities that can be found in Rust code.

Goals

Achieve a beginner/intermediate level of proficiency in writing Rust code. This will be measured by trying to solve LeetCode problems focusing on common data structures and algorithms. Study Rust vulnerabilities and learning best practices to avoid them.

Resources

Arcticwolf - A rust based user space NFS server by vcheng

Description

Rust has similar performance to C. Also, have a better async IO module and high integration with io_uring. This project aims to develop a user-space NFS server based on Rust.

Goals

• Get an understanding of how cargo works
• Get an understanding of how XDR was generated with xdrgen
• Create the RUST-based NFS server that supports basic operations like mount/readdir/read/write

Result (2025 Hackweek)

• In progress PR: https://github.com/Vicente-Cheng/arcticwolf/pull/1
