Top 6 Rust Frameworks To Use In 2019

Rust is used to build quick, highly scalable, memory- efficient software. Regardless of whether you’re building a CLI tool, web applications for the server or client, network services, embedded systems software or desktop software, Rust is robust enough to cater all your programming needs.

A framework is typically a combination of tools, helpers, and also libraries that give an approach to (rapidly and easily) build, test, and run applications. It establishes a foundation for building software. Key viewpoints to look out for when selecting a framework are its architecture and features, (for example, support for customization, flexibility, extensibility, security, compatibility with different libraries, and so forth).

This article aims to feature some Rust frameworks across various niches, featuring their strengths and weaknesses also. Before the end, you can able to make informed decisions in regards to the Rust framework appropriate for your needs.

Best Rust frameworks in 2019-

1. Rocket-

Rocket is one of the most developed, production ready, full- stack web frameworks. It’s major strong point is that it doesn’t make you sacrifice speed for a productive environment and vice versa like other frameworks. It helps to write fast and also secure web applications.

Advantages of Rocket-

  • It supports JSON out of the box so you don’t need to have another dependency for that.
  • Form handling is easy and simple. It doesn’t allow bad form requests through. Hence your code doesn’t break. It gives you complete control over all aspects of your application.
  • It has a built- in templating support.
  • You can view, add, or remove cookies, with or without encryption, without issue
  • It runs unit tests on your applications effortlessly using the built- in testing library.
  • You can configure your application as per your requirement for development, staging, and also production.

One of the best features is not having to worry about boilerplate code. Rocket utilizes Rust’s code generation tools to provide a clean API, so if you need to build a server-rendered web application, Rocket is a great tool.

2. Actix-

Actix is a server- rendered framework. The architecture is depends on Rust’s very powerful actor system. Actix is the fastest web framework to work with. It’s appropriate for writing services with hard logic and components. You get to also utilize these services in an async way.

It also gives a lot of features like logging, http/2, and so on. As per your preference, it’s standard code could assist you with started rapidly or be overkill if you’re writing a simple app. It is a great framework with appropriate documentation. 

3. Nickel-

Nickel is also a web framework for building server- rendered web applications. It is simple and also lightweight foundation for web applications written in Rust. Its API is motivated by the popular express framework for JavaScript.

It is non-opinionated about how you should write your code which implies it doesn’t come with a template or give specific methods for getting things done and has a more gradual learning curve. Nickel supports defining formats with, all you need is to make the template.

Nickel makes it simple to map JSON data directly right onto your struct, and by default, Nickel gets all errors with its default ErrorHandler and attempts to take reasonable actions. So no need to write your very own custom errorHandler.

Routes can be as simple as /fizzBuzz, use parameters, wildcards or even double wildcards. Middleware are the extensibility purposes of Nickel. It comes directly out of the box with existing Middleware which you can extend should you wish to. 

4. Yew-

Inspired by Elm and React, Yew is a modern framework for building multi-threaded web-client applications with WebAssembly ordinarily referred to as WASM. It has various great features like:

  • Reusable component architecture
  • Another cool feature is services. They let you for the reuse of same logic across components. These services are stateless. It uses the concept of agents which is likewise used to share data across components and give a general state to your application.
  • It utilizes the WebWorkers API to generate agents in separate threads and uses a local scheduler attached to a thread for simultaneous tasks. This allows high concurrency applications within the browser written in Rust.

Cons of using Yew-

  • Testing isn’t totally wholesome in yew. You can test individual services yet there is no chance to get, to test components. Both integration and end-to-end testing can’t be accomplished in plain Rust.
  • Yew seems to be in its early stages and as such, there is not an  appropriate official guide on the best way to use it

5. Azul-

Same as JavaScript’s Electron, Azul is a free, functional, immediate- mode GUI framework for the rapid development of desktop applications written in Rust, supported by the Mozilla WebRender rendering engine.

Features of Azul-

  • OpenGL integration
  • Built-in controls for common user interface elements
  • Async I/O helper functions
  • XML serialization and hot-reload, built-in XML-to-Rust compiler
  • Create custom widgets via function composition
  • CSS styling engine, flexbox-based layout
  • Hardware-accelerated OpenGL rendering (0.5 – 4ms)
  • React-like DOM diffing for incremental layout and styling changes
  • Cross-platform GUI toolkit (Windows, Linux, Mac)
  • Immediate-mode API, widgets are composed via function composition
  • SVG rendering engine, 2D drawing helpers
  • Single deployment binary, minimal binary size (roughly 5MB all-incl.), CPU (0 – 4%) and RAM usage (~ 50MB total)

6. Conrod-

Conrod is a portable, 2D, GUI library for Rust. It gives an immediate mode API that wraps a retained mode widget state graph, allowing for the exposure of a simple, robust and reactive interface while moving toward the performance of traditional, retained GUI frameworks.

Intermediate mode refers to a style of user interface API, where GUI widgets are started using functions in an update or draw loop which is very unique from the more traditional “retained mode”, where widget types are developed during the setup stage.


  • An easy to use style for more dynamic interfaces and those that require frequent synchronization with application state
  • Highly performant
  • It however needs lots of stabilization. 

Final words-

These are some Rust frameworks that you can use. Apart from these, there can be other frameworks also. Some of them are for web development, while others are for desktop application development. Select the best one according to development you need.

Selecting the best one among them is important as it eases your development with great features. You can consult with solace experts to choose the best one.
