How to Contribute to Rust Crates and Improve the Community

If you're a seasoned or new developer who's passionate about the Rust programming language and wants to be a part of its rapidly growing community, there are many ways you can contribute. One way to start is by contributing to Rust crates. Rust crates are libraries or collections of code that you can use to build software applications.

In this guide, we'll take a closer look at what Rust crates are, why contributing to them is important, and how you can get started. So, let's dive in!

What Are Rust Crates?

In Rust, crates are the basic unit of code reuse. A crate is essentially a library or a package of Rust code that can be shared with others. Each crate can contain modules, which are nested sets of code that can be used to organize functions and types.

Crate names in Rust must be unique, and they can either be hosted on, the Rust community's official package registry, or on the developer's personal GitHub repository. Each crate on can have one or more contributors who have added code to it over time, making them a great way to get involved with the Rust community and contribute to its growing ecosystem of libraries.

Why Contribute to Rust Crates?

There are many benefits to contributing to Rust crates. For one, you'll help to improve the quality of software that relies on them. By providing bug fixes, functionality improvements, or other changes, you'll make crates more reliable, efficient, and user-friendly, making it easier for other developers to build Rust applications.

Contributing to Rust crates can also help you learn more about programming in Rust. Being part of an active community like Rust's can help you grow your skills as a developer by giving you access to best practices, keeping you up to date on new features and tools, and providing a platform to ask questions and learn from others.

How Can You Contribute to Rust Crates?

There are several ways to contribute to Rust crates, depending on your experience level, interests, and skills. Here are a few of the most common:

1. Use and Test Rust Crates

One of the most important ways to contribute to Rust crates is by using them and providing feedback. By testing the functionality of a crate, you can help identify contradictions or areas for improvement that the creator can then address. Reviewing the code quality and implementing best practices can also assist the crate owner in enhancing the crate.

2. Report Bugs and Issues

If you find a bug or any other issues in a Rust crate you're using, report it as soon as possible to the crate owner. Providing feedback on the crate's source code and documentation can help make future changes more effective and practical, making it more comfortable for everyone. Checkouts through clippy can also help in identifying issues that should be resolved.

3. Submit Pull Requests

Pull requests are an integral part of contributing to an open-source project such as Rust crates. They are the primary way you can submit your changes, suggestions, or patches to the original crate. It's the simplest way to provide a bespoke solution to a problem you identified while using the crate. Submitting pull requests is a great way to start with community contribution, and it helps you learn more about Rust code development and best practices.

4. Improve Crate Documentation

The process of understanding a crate begins with the documentation. Hence, improving that aspect can make the crate more approachable and easier to use. If you're good at writing documentation or feel like there is something that you can add to the crate's documentation to make it more accessible to others, do so. Begin by familiarizing yourself with the crate and its API, and then file an issue or reach out to the library owner for suggestions. Documenting can also involve creating new demos and examples for crates to highlight their capabilities.

5. Maintain Rust Crates

As a developer with a good understanding of the crate's codebase, you can take the initiative to become a crate's maintainer. There are plenty of Rust crates that need maintenance, such as updating dependencies, reviewing bug reports and pull requests, responding to issues, and testing new releases. If you're up to the task of managing a crate, reach out to the owner and offer to help. Being a maintainer can help you build a strong reputation among the Rust community and create a more significant impact on the ecosystem.

Getting Started with Contributing to Rust Crates

Now that you know some of the ways you can contribute to Rust crates, you're ready to get started! Here are a few steps you can follow to help you begin:

1. Find Rust Crates to Contribute To

The first step to contributing to Rust crates is to find crates that you'd be interested in working on. You can start by checking the Rust community's main crate repository,, or by trying to utilize any of the Rust crates you know exist in your projects. Look for crates that you enjoy using or that you think could benefit from your contributions the most. Some crates might have an Issue, Good first issue, or Help wanted tag that could give you a point to start. Furthermore, other crates might require updating or improvement, and it's always great to add new features to existing crates.

2. Familiarize Yourself with the Crate

Before making any pull requests or contributions, you should take the time to read through the crate's documentation, source code and run tests. This will help you understand what the crate is used for, how it works, and what contribution approach would be appropriate. You should also check if the crate's issues section has a tag indicating the area where you could contribute.

3. Start Small

When fixing a bug or contributing to a Rust crate, start by identifying the smallest possible change that can address your concerns. This approach allows you to get familiar with the codebase, file an issue, learn best strategies for pull requests, and eventually get recognized as a contributor to the community. Starting small also makes it easier to get feedback and ensure that your contributions are valuable to the crate.

4. Collaborate with the Rust Community

When contributing to Rust crates, it is essential to obtain feedback from the community. You can submit pull requests or file issues and ask for a review from the crate maintainers and other developers. Engaging with the community can help you learn more about best practices, open-source technologies, and get critical feedback that improves your code writing skills.

5. Keep Learning and Growing

Finally, keep learning and growing as a developer. Contributing to Rust crates can help you hone your skills, learn new Rust programming techniques, and become a better developer, you should take every opportunity to learn and support others. Thanks to the Rust community's diversity and innovation, learning Rust crates can be an exciting and rewarding journey.

Wrapping Up

By contributing to Rust crates, you can make yourself productive, develop essential skills, and enhance the Rust programming language ecosystem. Remember, contributing to Rust isn't just about writing code or optimizing the codebase—it's about becoming part of a collaborative, passionate, and welcoming community that is critical in promoting open-source software development.

We hope this guide has given you some ideas on how you can get started with contributing to Rust crates, and that you find your journey to be rewarding and fulfilling. Happy coding!
