[TWiR] Call for Participation

Hello Rustaceans,

Inspired by the "contributors wanted" wiki, starting issue 120 of This Week in Rust, there will be a new section "Call for Participation" which will highlight tasks from Rust community projects, specially to newcomers who want to get started with contributing to open-source projects.

If you are looking for contributors for your Rust project, please reply to this thread with a link to the task in your issue tracker.

Some guidelines to follow while submitting your task:

  • Ensure that your project has at least one open-source licence. (we've decided to not define the term "open-source" and it is left to your own interpretation).
  • Ensure that the issue tracker for your project is publicly accessible.
  • Create a new issue in your issue tracker and clearly describe the task. Also mention the difficulty level (easy/medium/hard/tedious), either as a tag/label or somewhere in the title/description.
  • If you have specific requirements for contributors (e.g., copyright waiver), it must be mentioned in the description of the task (preferably with a link to CONTRIBUTING.md).

Also take a look at Manish's great guide on making your open-source project newcomer-friendly.

Suggestions & feedbacks are welcome. I also welcome suggestions for a better section name.


Here are some recent mentored bugs for Rust that @Manishearth put together: Etherpad Mozilla


I've recently started adding new-contributor-friendly labels to the issues on cargo-edit. You can find open cargo-edit issues here.

If I understand correctly, you want me to link to one task? Okay, here it is:


I just added difficulty tags to buildengine5. It's a early prototype engine for 2d tile based top-down games like Space Station 13. Currently it only has basic networking capabilities, however I'm just starting to add a scripting engine.

One issue I'd like to highlight is #10. I've been stuck on it for way too long, and I'm sure it's some stupid thing I've overlooked.


I'm looking for someone who could implement a memory pool struct in Vulkano. In other words, an implementation of a malloc algorithm but to allocate video memory instead of regular memory.


Here are two for rustup:



I've gone through my rexiv2 project (a library for working with media file metadata, such as photo Exif, XMP, and IPTC tags) to make it more newcomer-friendly. I've added setup instructions and a contributing guide, and tried to identify and tag issues in the tracker that would be good first bugs.

They're all listed under that tag, but if I had to pick just a couple, I'd recommend

I'm happy to help new contributors, whether new to just the project or to Free/Open Source software in general. The only caveat is that I myself am not particularly experienced in Rust, so for newcomers to the language I'll be figuring things out along with them.

I've carved out a ticket for decreasing the memory usage of the DFA in regex: decrease memory usage of DFA with variable width delta encoding of instruction pointers · Issue #199 · rust-lang/regex · GitHub --- Depending on past experience with FSAs, I'd put this at medium/hard.

@nasa42 Here's a new batch of easy rustup bugs. I believe I've given enough instructions to solve them.

Here's one for tokei. The only work is knowing string literals in other languages.

Some work for Tera!


We need some help in SUPER for the next version :slight_smile: here are three issues that would greatly benefit from help from other contributors.


We have the medium difficulty written as D-Moderate in our labels. The rest should be the same. The D- prefix comes from difficulty.

I've got an easy task for Maud:


I just published a small crate that can reverse strings in-place while correctly handling multi-byte and multi-codepoint graphemes. But it requires unsafe code, so I'd love help making sure my code coverage is adequate:

Here again for Tera!

A few easy tasks:

A little harder:

I just file one easy, good first bug for gimli (a DWARF debugging information library).


Would love to mentor someone on this :slight_smile:

Compiling an Android package with cargo-apk mostly works technically, but many command line options are missing. For example right now you can't even compile a package that has multiple binaries because there's no way to specify the one you want.

If you are familiar with CLI libraries, I'm not against some help:

Here is some work for tokei. It should be [easy-medium] depending on the package manager and how much work is actually involved.


For someone who is interested in implementing crypto hashes or block ciphers:
Difficulty of straightforward implementation of one algorithm can vary, but i think will be around medium. Though writing optimized version can be quite hard.

There are a few "easy for newcomers" issues on diesel, e.g.:




You are very welcome to list these in TWIR and also have a look at the other open issues :slight_smile:
