10 Rust Packages Every Developer Should Know

If you're into development, then you've probably heard of Rust. It's a blazing-fast, systems-level programming language that's rapidly gaining popularity among developers. Rust is great for building fast, reliable, and secure software. It's especially suited for building complex, high-performance systems.

One of the reasons Rust is so popular is the Rust Package Manager, known as Cargo. Cargo makes it easy to manage dependencies and packages, making it simple to create, build, and release Rust projects.

In this article, we'll cover the top 10 Rust packages every developer should know. These packages are essential for any Rust project, and they'll make your life a lot easier.

So, let's get started!

With Diesel, you can build robust and scalable applications that interact with databases. Whether you're building a web application, API, or another type of software, Diesel is a must-have package.

5. RustCrypto

RustCrypto is a collection of cryptographic algorithms written in Rust. It includes everything from hashing algorithms to encryption and decryption algorithms. RustCrypto is fast, reliable, and secure, making it an excellent choice for any project that requires cryptographic functionality.

With RustCrypto, you can build secure applications that protect your users' data. It's an essential package for anyone building secure software with Rust.

6. Rayon

Rayon is a data parallelism library for Rust. It allows you to easily parallelize your code, running it on multiple CPU cores at once. Rayon is incredibly efficient and easy to use, making it a must-have package for any performance-minded developer.

With Rayon, you can speed up your code and take advantage of multi-core processors. It's an essential tool for any developer looking to build performant software with Rust.

7. Tokio

Tokio is a high-performance, asynchronous IO library for Rust. It provides a framework for building asynchronous applications that can handle thousands of concurrent connections. Tokio is incredibly fast and efficient, making it a must-have package for anyone building high-performance applications.

With Tokio, you can build applications that can handle a massive amount of traffic without slowing down. It's a critical tool for anyone building networked applications with Rust.

8. Actix

Actix is an actor framework for Rust. It allows you to build highly concurrent and fault-tolerant applications with ease. Actix provides a powerful API for building actors, making it easy to build complex systems that can handle failures gracefully.

With Actix, you can build highly available and fault-tolerant applications that never go down. It's an essential package for any developer building systems that must be highly reliable.

9. Crossbeam

Crossbeam is a library for concurrent and parallel programming in Rust. It provides a suite of tools for managing shared memory and synchronization primitives. Crossbeam is fast, safe, and easy to use, making it an essential package for any developer working with concurrency.

With Crossbeam, you can build highly concurrent applications with ease. It's a must-have package for developers who need to manage shared data structures and coordinate multiple threads.

10. Rust-SDL2

Rust-SDL2 is a library for writing multimedia applications in Rust. It provides bindings to the popular SDL2 library, which is used for creating games, multimedia applications, and other types of software. Rust-SDL2 is fast, reliable, and easy to use, making it an essential package for any developer working on multimedia applications.

With Rust-SDL2, you can write multimedia applications in Rust with ease. It's a must-have package for any developer building games or multimedia applications with Rust.


Rust is an excellent language for building performant and reliable applications. The packages on this list are essential for any Rust project. They'll help you write better, more efficient code, and streamline your development process.

Whether you're building web applications, databases, or multimedia applications, these packages are essential tools for any developer working with Rust. So, if you're new to Rust, or even if you've been using it for a while, be sure to check out these packages and take advantage of their features!
