What are the scenarios where "Rewrite it in Rust" didn't meet your expectations or couldn't be successfully implemented?

• embassy

  70 4,377 9.9 Rust

  Modern embedded framework, using Rust and async.

  

The embassy ecosystem is good. Then you bring async into the equation, which fits embedded really well. I've been working full time with embassy for the last 10 months or so and love it.

• rust-openssl

  7 1,320 9.1 Rust

  OpenSSL bindings for Rust

I also studied this question on FFI several weeks ago in terms of "rewrite part of the system in Rust". Unexpected results could be semantic issues (e.g., different error handling methods) or security issues (FFI could be a soundness hole). I suggest going through the issues of libraries that have started rewriting work such as rust-openssl or rustls (This is the one trying to rewrite in whole rust rather than using FFI; however, you will not be able to find the mapping function in the C version and compare them). I hope this helps!

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• rustls

  57 5,437 9.9 Rust

  A modern TLS library in Rust

• midi-to-keypress

  7 88 0.0 Rust

  Takes MIDI input and turns it into keypresses

I did this a few years ago with https://github.com/xobs/midi-to-keypress and the biggest issue I faced was the lack of a gui.

• CircleMUD

  5 59 0.0 C

  Unofficial mirror of the CircleMUD engine.

Unfortunately the server has a blocking select until there's a new socket for when there's no open sockets to manage. I either have to change the old logic or write some awkward condvar stuff (like here https://github.com/Yuffster/CircleMUD/commit/94c27cc11fda671ede5316e6aadc170889060f5e). It's really sad, the naive version that busy loops when the server has no connections is very chic and then it gets a lot harder to follow.

• kanata

  62 1,175 9.5 Rust

  Improve keyboard comfort and usability with advanced customization

• Clipper2

  1 1,222 8.8 C++

  Polygon Clipping and Offsetting - C++, C# and Delphi

I tried to rewrite Clipper2 in Rust. There's a C#, a Delphi and a C++ implementation, so how hard can it be?

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• winsafe

  41 439 9.4 Rust

  Windows API and GUI in safe, idiomatic Rust.

If you had such problems (which I also had in the past), I'm really interested in you opinion about WinSafe, and if it could help you solving them.

• Relm4

  23 1,310 8.9 Rust

  Build truly native applications with ease!

  

Did you try Relm? It's an implementation is the elm architecture (think react) on top of Gtk. Given your experience with Gtk it might suit you really well, as you can even take only parts of it and continue using bare Gtk for the rest. Give it a try!

• inline-python

  5 1,112 3.9 Rust

  Inline Python code directly in your Rust code

  

This may be cursed but you could just use https://github.com/fusion-engineering/inline-python to use the Python Levensthein library in Rust directly. Just make sure to invoke the Rust binary under a venv with the library

• VulkanDemo

  1 0 1.9 C

  A cross-platform spike using Vulkan to render a complex, lit and shadowed environment.

Sure. Unsure how readily a rusty person could port, say, my Vulkan repo https://github.com/cschladetsch/VulkanDemo

• xml-mut

  4 4 3.8 Rust

  xml mutation language resembling sql

This is exactly what I needed when implementing xml-mut :D I have used roxmltree instead and manipulated text directly. will try to rewrite it using Xot.

• roxmltree

  4 403 7.3 Rust

  Represent an XML document as a read-only tree.

This is exactly what I needed when implementing xml-mut :D I have used roxmltree instead and manipulated text directly. will try to rewrite it using Xot.

• quick-xml

  4 1,094 9.2 Rust

  Rust high performance xml reader and writer

Exactly the same experience. In particular I ran into the issue that the only "ergonomic" API (that doesn't require hand-writing a parser) uses serde derive macros, but quick_xml doesn't handle namespaces. After about a day of this I stopped bike-shedding and just used lxml in Python. It works fine (and I have a large XML file, ~2.4Gb).

• avr-hal

  30 1,183 8.7 Rust

  embedded-hal abstractions for AVR microcontrollers

I found the generics a lot less of a problem when I realized I could parametrize on things like embedded_hal::serial::Write instead of UsartOps https://github.com/Rahix/avr-hal/pull/264/commits/17ed15321cb8fcf8aedb1f8133be1f189eb06a6f
