[TWiR] Call for Participation

Three issues in ruma-client-api with difficulties from easy to hard:




The vast majority of Tetra (a 2D game library) is safe Rust, but the OpenGL abstraction layer uses a lot of unsafe, which I have very little confidence in :sweat_smile:

I've created a tracking issue to discuss safety - if anyone could pitch in and save me from silly mistakes, it'd be helpful!


Wait.. so what have we been using all this time?

Very beginner friendly. I need some test coverage for the futures-jsonrpc crate


Difficulty: Medium


I have something a bit different, I don't know if it fits here.

I asked a question on StackOverflow: What are the similarities and differences between C++'s concepts and Rust's traits? I know a lot of people that are really interested in an answer to it. @matthieum already attempted to answer it (which I am very happy about), but they mention that they have not yet worked with concepts " so take this answer with a grain of salt.".

It would be cool to maybe find someone who really knows C++ concepts to answer this question. So I thought that we can maybe add this to TWiR to reach a wider audience? Something like:

Do you know a lot about C++ concepts? Please consider answering this question or improving existing answers (e.g. by pointing out flaws): What are the similarities and differences between C++'s concepts and Rust's traits?

I will also add a bounty to the question in a few days (before the next TWiR is released).

eazy and tedious, requires building large projects.

This is waiting on someone with a fairly powerful and idle computer doing a comparison of time cargo generate-lockfile with a build of master vers a build with this PR on some large project like servo or like rustc.

Hi, I include a renaming issue:

Solving this issue should require basic familiarity with Rust, no additional knowledge about the Offst project is required.

This linear algebra library needs more tests, easy issue if you know linear algebra.
You can see what the functions are supposed to do from netlib.

We could use a more experienced embedded developer to help us with a problem in the Rubble BLE stack.

I could use some help with the ConTrie crate. I've created two tickets for some of the work that needs to be done, both is writing code that is similar to some other code already in the crate so it should be quite beginner friendly.

I'm the Windows maintainer of Winit. We could use some help getting stuff done on... well, all platforms, really, but especially macOS, X11, Android, and iOS.


I have two simple and self-contained issues for new Rustaceans in my new crate js_int:



There's another one that might be harder, but probably is relatively easy too:

Here are some simple rustc-guide documentation issues that would be really good candidates for first PR's to rust:

For Hacktoberfest I'd like to get my crate rustfm-scrobble to v1.0.

I've been working on it for a few years, it's a very simple little crate - a small API client for Last.fm's Scrobble API. There are a few issues left before a 1.0 release, all of them on GitHub with the 'Hacktoberfest' label.

Good opportunity to get some Hacktoberfest PRs and work on improving the Rust ecosystem.

Tokamak and Bastion looking for maintainers!

My static_assertions crate is now 1.0! :slight_smile:
