Rust libraries and frameworks: A comprehensive guide

If you're new to Rust, you might be wondering what libraries and frameworks exist for this versatile language. Rust is perfect for software engineers who want to create fast, safe, and reliable code. The language achieves this through its ownership concept and borrow checker that ensure memory safety and thread safety.

But how do you get started with Rust libraries and frameworks? Well, you're in the right place. In this guide, you'll learn about Rust libraries and frameworks that can help you get your projects off the ground.

What Are Rust Libraries and Frameworks?

Before we dive into the nitty-gritty, let's start by clarifying what we mean by Rust libraries and frameworks.

Rust Libraries

Rust libraries are collections of code that perform specific functions. Libraries are pieces of code that you can include in your Rust project. With a vast collection of libraries willing to let you use their code, Rust developers can build more complex software solutions quickly without having to write everything themselves.

Rust Frameworks

Rust frameworks, on the other hand, differ from libraries in terms of their organization and purpose. While libraries are code collections that you use to complete certain tasks or solve specific problems, frameworks provide structure and guidance on the entire project.

Frameworks can be used as templates to build a new software solution. Instead of starting from scratch, you can use a framework to ensure your project has a standard organization, supplies common functionality, and offers tutorials or documentation to assist you in starting.

Rust frameworks provide a high-level framework with lots of pre-built, pre-tested code. A Rust framework offers a unique focus on ease of use and convenience, providing a way to build a high-quality application with minimal effort, much like what Ruby on Rails provides for Ruby and Django provides for Python.

The Best Rust Libraries and Frameworks

Okay, let's now explore some of the best Rust libraries and frameworks.

The Rust Standard Library

Before you move on to other frameworks or libraries, it's important to understand and master the Rust standard library. Rust provides an extensive collection of modules, constants, and types that enable developers to build high-quality, efficient, and safe code.

The standard library in Rust is accessible from any Rust program by simply typing use std; at the top of your code. The Rust standard library also includes core::mem and core::ops, core::str, core::clone, core::marker, core::fmt, core::cell, core::ptr, core::fault, core::num, core::collections, core::hash, core::sync, core::thread, and many other modules.

The Rust standard library provides excellent documentation, and this is an excellent starting point for developers looking to write efficient and high-quality Rust code.


Rocket is a Rust web framework that prioritizes productivity and ease of use, offering an elegant solution for developers looking to build fast, safe, and concurrent APIs.

Rocket provides type-safe routing and request handling, blazing fast templating, and an expressive API. One great feature of Rocket is it automatically manages JSON serialization and deserialization, making it easy to create API endpoints for your application.

Documentation for Rocket is extensible and thorough, and the framework offers performance benchmarks for the most commonly used functionality.


One of the most popular Rust frameworks, Actix, is an actor-based application development framework that offers high performance and scalability. Actix provides a range of features including RESTful service, send messages to actors in nonblocking, service discovery, actor supervision, transparent remote actors, and WebSocket support.

Actix is designed to work with a range of systems, and its flexible design means that it is suitable for microservices development, IoT applications, and other projects that require the implementation of complex processes.

Documentation for Actix is thorough, and the framework is well-maintained with active development.


Rust's Diesel framework is an ORM that allows you to interact with databases in a type-safe and efficient manner. Diesel is inspired by ActiveRecord ORM, and it provides more advanced querying features that aren't found in other ORMs. The framework also includes support for a wide range of databases.

Diesel helps remove the pain from database programming by managing the state of database entity objects, improving performance for large sets of data, and helping optimize database queries. Diesel also offers a lot of convenience functions and macros that make writing SQL question much easier.


Serde is a library for Rust that allows developers to serialize and deserialize Rust data structures. Serde provides automatic support for JSON, Toml, and CSV among others. Serde is an excellent library whenever data needs to be passed across API boundaries, as its automatic data serialization and deserialization provide the perfect blend of safety, idiomatic expressiveness, and efficiency.


Tokio is a performative runtime built for Rust, which enables the creation of high-concurrency systems. Tokio provides an event-driven and non-blocking programming model. Using Futures and Async IO, Tokio enables you to write performant systems without sacrificing compliance with modern system design principles.


Proptest is a Rust library that helps with automated testing of the inputs for a program. It works by generating random data that feeds into the programs being tested. By testing programs with comprehensive sets of data points instead of a few arbitrarily chosen input sequences, Proptest ensures the functionality of the program is spot-checked with better accuracy than manual testing.


In conclusion, Rust is a powerful language with a growing collection of libraries and frameworks to help software engineers build fast, efficient, and safe programs. Whether it's web development, databases, actor systems, or automated testing, Rust has something to offer.

We've covered some of the most prominent Rust libraries and frameworks today, but this is just the tip of the iceberg. So, get started with Rust today and explore the vast world of Rust libraries and frameworks to create fast, safe, and reliable code.
