Rust vs. Go: How to Choose

In less than a decade, two new programming languages have emerged as major options for enterprise development: Go, which was created at Google, and Rust, which was created at Mozilla.

Both languages offer indispensable features for modern software development: a sophisticated and integrated toolchain, memory safety, an open source development model, and strong communities of users.

Apart from those similarities, Rust and Go are dramatically different. They were built to scratch different itches, fulfill different demands, and write different kinds of programs. Thus, comparing Rust and Go isn’t about which language is “objectively better,” but about which language is best for a given programming task. With that in mind, let’s look at the main ways Rust and Go differ, and the kinds of work each is best suited for.

Rust vs Go | Which Programming Language to Choose Between Go & Rust

A detailed comparison between Rust vs Go programming languages: What is Rust and Go, pros & cons, similarities and differences between Go and Rust, and more

Are you an entrepreneur or a senior enterprise IT leader who is planning to undertake a web development project? You might be wondering which programming language to use. In relation to this, you might have come across programming languages like Rust and Go. You are probably weighing between Rust vs Go and trying to decide which one to use in your project.

Both Rust and Go are increasingly popular languages. Which one fits your requirements better? What are their pros and cons and which one should you choose? In this guide, we answer all of these questions so that you can make an informed decision. Read on!

Rust: An introduction

Graydon Hoare designed Rust while working with Mozilla Research. There were other contributors too, e.g., Dave Harman, and Brendan Eich. Rust is a statically-typed, compiled programming language. It’s an open-source language, and its syntax is similar to that of C++.

The first release of Rust came in 2010. Since then, developers have enhanced this language significantly. At the time of this comparison, the latest stable release of Rust is 1.42.0, which came in March 2020. Several well-known organizations use Rust, e.g.:

  • Mozilla;
  • Dropbox;
  • Qiwi;
  • Brilliant;
  • Sentry;
  • Postmates;
  • Wantedly.


Piston, the popular game is built using Rust. Mozilla is building Rust to build Servo, a new browser engine.

Rust: Where can you use it?

A relatively new language, Rust can have varied usage. You can use Rust for systems programming.

Rust offers memory safety, moreover, this statically-typed language reduces common programming errors. As a result, if you are building a large system where security is very important, then you can use Rust. By its very design, the language reduces application security vulnerabilities.

Rust also offers speed. This makes it a good candidate for developing game engines, operating systems, file systems, and browser components. Its performance also makes Rust a smart choice to build “Virtual Reality” (VR) simulation engines.

Go: An overview

Rob Pike, Robert Greisemer, and Ken Thompson developed Go jointly. They developed it in 2007 at Google, however, they launched it for the first time in 2009. Go, or “Golang” as it’s often called, is an open-source programming language. The developers of Go modeled it after C. Go is a statically-typed, compiled language.

Go has gone through several rounds and developments. At the time of writing this article, its last stable release is 1.14.1. This release came in March 2020. The following are a few examples of well-known organizations that use Go:

  • Google;
  • Apple;
  • Facebook;
  • Twitter;
  • IBM;
  • Dropbox;
  • BBC.


A few popular applications developed in Go are Netflix, Dropbox, Docker, and Kubernetes.

Where can you use Go?

Go is a versatile language and you can use it for several purposes. To be more specific though, you can use Go whenever you need to build a highly modular application system with high security and high speed.

You can use it for system programming and network programming. The language also has prominent usage in web app development, alternatively, you can use Go in applications involving big data or machine learning.

You can use Go to create command-line apps or scripts. If you are building a large, distributed system, then you can use Go. Finally, you can use Go to build highly-scalable network servers. Go has a lot of flexibility.

The advantages and disadvantages of Rust

rust-pros-and-consWhat are the pros and cons of Rust? It offers the following advantages:

  • Achieve more while coding less: Rust supports more complexity than several other programming languages, therefore, you can achieve more with it. E.g., it supports generics. You will find it easier to build powerful web apps using Rust.
  • Quicker debugging and testing: You will find debugging and testing easier with Rust.
  • Rust enables cross-platform development.
  • Performant: Rust offers robust performance.
  • The ease of integration: You can integrate Rust easily with C and several other popular languages.
  • Safer programming: Rust enables you to eliminate errors, which results in fewer application security vulnerabilities.
  • Strong community support: There is a vibrant developer community that supports Rust.

There are a few disadvantages to Rust as well, which are as follows:

  • Learning curve: Developers might take longer to learn Rust due to its complexities.
  • Less efficient: It takes longer to compile Rust and the code can be less efficient.
  • Maintenance can be harder: Since Rust has more complexities, you could end up spending more effort to maintain apps written in it.
  • It will take longer to build a large ecosystem since Rust is a relatively new language. Take the case of web development frameworks for Rust. Actix, Rocket, and Nickle are some of key web development frameworks for this language. Its illustrious competitors in the market are more established, and they have many more popular frameworks.
  • Limitations in comparison to leading programming languages: Rust can leak memory in some cases, moreover, it can be slower than some popular languages.

Go: Its pros and cons

Go is a popular programming language since it offers several advantages. These advantages are as follows:

  • The ease of use: Programmers can understand Go easily, which results in several advantages for organizations. The language features an easy-to-use syntax, therefore, new developers can learn it easily. If you use Go, then your maintenance becomes easier.
  • You can do more with less, thanks to the library of Go. Go comes with a powerful yet simple standard library. Programmers can achieve a lot without creating complex pieces of code, thanks to this library! Developers coding in Go don’t need to import secondary libraries.
  • Security-friendly language: Since Go is a statically-typed language, the chances of error reduce. That’s an advantage over dynamically-typed languages with a large number of variable types and higher chances of complex coding errors. Also, code written in Go is simpler and easier to debug. The combination of these factors reduces application security vulnerabilities.
  • Support from Google: Go has seen important developments and enhancements, and you can count on this trend to continue. Google supports it, and that speaks well for the future of Go.
  • Excellent documentation: Not only does Go have excellent documentation, but it goes a step further. Developers that didn’t document their code sufficiently get alerts to put in place the required documentation. This adds to the maintainability of code written in Go.

Rust vs. Go: Should I Rust, or Should I Go

Should I stay, or should I go?” Great song by the band The Clash. I’m listening to it, right now, while I’m writing this article. The song debuted back in 1982, a long time ago. Back then, I was just a kid exploring a new hobby — programming my Atari 2600. The first video game I ever wrote was written using 6502 Assembly for that console. The compiler for it cost about $65, if I recall, which at the time equated to mowing ~13 or so lawns.

The game was simple: using the joystick, maneuver your spaceship through a randomly generated scrolling cave. The cave walls were sinusoidal, scrolling vertically on the left and right sides of the screen, and you had to make sure your craft didn’t crash into them. I know, I know: Not that sophisticated. But I was only ten or eleven years old at the time.

Despite the “power” of the processor, computing sine values at run-time was simply too much for it. So, using my handy Texas Instruments calculator, I pre-calculated a bunch of the sine values, carefully writing them down on paper, and then entering them in as constants for the game. This greatly enhanced the performance of the game, and made it usable.

So what’s my point? What’s any of this got to do with Rust or Go?

Today’s languages are far more advanced than 6502 Assembly, which make it easier to write complex programs. It took a lot of my time to write that game, and I could do it much faster today, with less code than I did back then. But which language today provides that magic combination of simplicity and power?

Well both Rust and Go provide amazing performance. They both compile to machine code, the Holy Grail of performance. And with today’s processing power, developers can do amazing things with either of these languages. So the question is: Should you write you’re next big thing with Rust or with Go?

With a quick search, you can easily find several articles that go into detail about the differences between the two languages. But the focus of this article is the bang for the buck, that magic combination of performance per line of code.
Should I Rust, or Should I Go

To put it another way, where is that sweet spot of simple code and top-end performance? And in this case, is it Rust, or is it Go?
There really isn’t any argument: Rust is faster than Go. In the benchmarks above, Rust was faster, and in some cases, an order of magnitude faster.

But before you run off choosing to write everything in Rust, consider that Go wasn’t that far behind it in many of those benchmarks, and it’s still much faster than the likes of Java, C#, JavaScript, Python and so on. So in other words, it’s almost a wash between Rust and Go on the axis of performance. Now, if what you’re building needs to wring out every last ounce of performance, then by all means, choose Rust. But if what you need is top-of-the-line performance, then you’ll be ahead of the game choosing either of these two languages.

So then we’re down to the complexity of the code. This is where things can be muddy since this can be more subjective than performance benchmarks. Let’s look at a simple exercise: building a small web server that prints out “Hello World” when it receives an HTTP request. To do this in Rust, it looks something like this:

use std::net::{TcpStream, TcpListener};
use std::io::{Read, Write};
use std::thread;

fn handle_read(mut stream: &TcpStream) {
    let mut buf = [0u8; 4096];
    match buf) {
        Ok(_) => {
            let req_str = String::from_utf8_lossy(&buf);
            println!("{}", req_str);
        Err(e) => println!("Unable to read stream: {}", e),

fn handle_write(mut stream: TcpStream) {
    let response = b"HTTP/1.1 200 OK\r\nContent-Type: text/html; charset=UTF-8\r\n\r\n<html><body>Hello world</body></html>\r\n";
    match stream.write(response) {
        Ok(n) => println!("Response sent: {} bytes", n),
        Err(e) => println!("Failed sending response: {}", e),

fn handle_client(stream: TcpStream) {

fn main() {
    let port = "8080";
    let listener = TcpListener::bind(format!("{}", port)).unwrap();
    println!("Listening for connections on port {}", port);

    for stream in listener.incoming() {
        match stream {
            Ok(stream) => {
                thread::spawn(|| {
            Err(e) => {
                println!("Unable to connect: {}", e);

Something pretty similar in Go looks like this:

package main

import (

type handler struct{}

func (theHandler *handler) ServeHTTP(writer http.ResponseWriter, request *http.Request) {
	log.Printf("Received request: %s\n", request.URL)
	log.Printf("%v\n", request)
	io.WriteString(writer, "Hello world!")

const port = "8080"

func main() {
	server := http.Server{
		Addr:    fmt.Sprintf(":%s", port),
		Handler: &handler{},


Now, they are not 100% exactly the same, but they are close enough. The difference between them is ~20 lines of code. Rust definitely forces the developer to consider more, and thus write more code than Go.

Another example: Consider one of the more difficult aspects of software development: multi-threading. When tackling something like this, as you undoubtedly would when building an HTTP server, there’s a lot to think about:

  • You need to ensure everything you design is thread safe (locks)
  • You need to handle communication between threads (channels)
  • You have to design with concurrency and parallelism in mind (threads and routines)

Both Rust and Go handle these hurdles really efficiently, but Go requires less effort. With Rust, you have way more options, and thus more power, when spawning threads. Just look at some of the documentation on this. Here’s just one way to spawn a thread in Rust:

use std::thread;

let handler = thread::spawn(|| {
    // thread code


On the other hand, here’s how to create something similar using Go:

go someFunction(args)

Another crucial part of writing code is handling errors. Here I think Rust and Go are quite similar. Rust enables the developer to handle errors cases through the use of the enum return types: Option<T>and Result<T, E>. The Option<T> will return either None or Some(T) whereas Result<T, E> will return either Ok(T) or Err(T). Given that most of Rust’s own libraries, as well as other third-party libraries, return one of these types, the developer will usually have to handle the case where nothing is returned, or where an error is returned.

Here’s a simple example of the Result type being returned by a function in Rust:

fn foo_divide(a: f32, b: f32) -> Result<f32, &'static str> {
    if b == 0.0 {
        Err("divide by zero error!")
    } else {
        Ok(a / b)
}fn main() {
    match foo_divide(5.0, 4.0) {
        Err(err) => println!("{}", err),
        Ok(result) => println!("5 / 4 = {}", result),

Notice that the Err case must be handled within the match statement.

Go, on the other hand, leaves this more up to the developer, since errors can be ignored using the _. However, idiomatic Go strongly recommends returning an error, especially since functions in Go can return multiple values. Therefore, it’s easy to have functions return their intended value along with an error, if there is one.

Here is the corresponding example from above done in Go:

func fooDivide(a float32, b float32) (float32, error) {
    if b == 0 {
        return 0, errors.New("divide by zero error!")
    }    return a / b, nil
}func main() {
    result, err := fooDivide(5, 4)
    if err != nil {
       log.Printf("an error occurred: %v", err)
    } else {
       log.Printf("The answer is: 5 / 4 = %f", result)

Notice that this line:

result, err := fooDivide(5, 4)

could have been written as

result, _ := fooDivide(5, 4)

In the latter case, the error returned would have been ignored.

Honestly, they’re both pretty similar, except for Rust forcing error checking. Otherwise, there’s little difference, and it’s difficult to find an advantage one has over the other. To my eyes, this is a draw.

I could keep going, digging deeper into other language differences. But the bottom line, from threads, to channels, to generics, Rust provides the developer with more options. In this respect, Rust is closer to C++ than Go. Does this make Rust inherently more complex?

I think so, yes.

So here are my recommendations:

  • Either. If you’re building a web service that handles high load, that you want to be able to scale both vertically and horizontally, either language will suit you perfectly.
  • Go. But if you want to write it faster, perhaps because you have many different services to write, or you have a large team of developers, then Go is your language of choice. Go gives you concurrency as a first-class citizen, and does not tolerate unsafe memory access (neither does Rust), but without forcing you to manage every last detail. Go is fast and powerful, but it avoids bogging the developer down, focusing instead on simplicity and uniformity.
  • Rust. If on the other hand, wringing out every last ounce of performance is a necessity, then Rust should be your choice. Rust is more of a competitor to C++ than it is with Go. Having battled with C++, Rust feels just as powerful but with many happy improvements. Rust empowers developers to have control over every last detail of how their threads behave with the rest of the system, how errors should be handled, and even the lifetime of their variables!
  • Rust. Rust was designed to interoperate with C. Go can as well, but gives up a lot to achieve this goal, and it’s not really its focus.
  • Go. If readability is a requirement, go with Go. It’s far too easy to make your code hard for others to grok with Rust.

I hope you enjoyed reading this!

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
