Rust vs Go: Top 9 Core Differences You Should Know

Are you thinking about which among Rust and Go will be best for your upcoming project? If yes, this blog on Rust vs Go will benefit you.

Although Rust and Go are not the most widely used languages, they are frequently compared by programmers who are considering adopting them.  Even though both of these programming languages share some important characteristics like an open-source development procedure, memory safety, and more, they are vastly different. 

With the capabilities of goroutines, Go has a larger focus on constructing web APIs and tiny services that can expand indefinitely. The latter is also feasible with Rust, although it is far more difficult from the perspective of A developer. Rust is a good choice for processing massive volumes of data and other CPU-intensive tasks like algorithm execution. Rust is better suited for projects that require high performance. 

In case you need any coding assignment help, such as Golang, or C++ assignment help, we have a team of experts who can help you at an affordable price.

Let’s start with a brief overview of both languages before diving deeper into Rust vs Go.

What Is Rust Programming?

Rust is a statically typed, general-purpose, multi-paradigm programming language primarily developed for performance and safety. We can also call Rust a systems programming language because, in addition to high-level capabilities like functional programming, it has mechanisms for low-level memory management.

It has generics, zero-cost abstractions, and functional features that eliminate the majority of the issues that other low-level languages have, such as memory errors and concurrent programming. With Rust, programmers can achieve Memory safety without garbage collection. Also, reference counting is optional. Many excellent websites and products, including Figma, Coursera, Cloudflare, NPM, Microsoft, Mozilla, Facebook, Dropbox, and more are developed using Rust.

Benefits Of Using Rust Programming

The major benefits of using Rust programming are as follows-

  • Good Memory Management and safety
  • Low Overhead
  • Easier concurrency
  • Cross-Platform Development Supported
  • Fast and High Performance
  • Concurrent Programming Support
  • Easy Maintainability

Popular Companies Using Rust

Here are some of the most well-known companies that are currently adopting Rust.

Dropbox

Rust code is used partially in Dropbox’s file-syncing engine. Because of its high concurrency, testing, writing, and debugging the engine is tough. Rust’s static types and thorough compile-time checks surpass dynamically typed languages like Python when dealing with concurrent code and complex projects.

Figma

Figma is a web-based design tool for creating vector drawings and prototypes of user interfaces. Because their server couldn’t keep up with user growth, Figma switched their multiplayer synchronisation engine from Typescript to Rust to boost performance.

Cloudflare

Cloudflare uses Rust programming in its core edge logic. It is a memory-safe replacement for the memory-insecure C language. According to Cloudflare, Rust is a strong alternative for appropriate performance.

Meta

The source control backend of Meta was originally implemented in Python and switched to Rust later. They required a compiled language to rewrite their source control backend, and Rust’s security characteristics drew them in. Since then, the source control team has switched to Rust.

What Is Go(Golang) Programming?

Go, or Galang is a compiled, procedural, statically types programming language designed originally at Google in 2007. It is an open-source programming language that mainly concentrates on reliability, simplicity, and efficiency. Golang was launched in 2009.

Go was designed primarily for networking and infrastructure-related applications. The main intention behind its development was to take the place of popular server-side languages like C++ and Java. Go adopts C’s static typing and runtime efficiency, as well as JavaScript’s and Python’s readability and usability. All of Go’s characteristics contribute to stability. Static type enhances flexibility by eliminating the need for explicit variable initialization. This contributes to the prevention of runtime faults and improves runtime efficiency.

By defining class via structure rather than declarations, structural type gives Go users more freedom. Garbage collection promotes memory safety by deallocating unneeded memory allocation. Concurrency refers to the ability for numerous processes to run at the same time, implying that programming processes run at lightning speed. Go also has high-performance networking and multi-processing capabilities. This also allows for speedier computation in general. These features are an additional benefit to code in Go that is designed to be simple to use and read.

Popular Companies Using Golang

Though the choice between Rust vs Go shouldn’t be based on popularity, understanding how and why prominent corporations choose Go will help you better understand the language’s potential.

Google

Golang was created by Google employees and is frequently used for internal projects at the company. This is how Google Chrome and Google Earth came to be. YouTube and Google App Engine both use it.

Dailymotion

Dailymotion is a video-on-demand platform. API automation has increased thanks to Golang and other programming languages.

This language enables the execution of a large number of automation tests that would otherwise result in massive loads. It’s all thanks to Golang’s ease of use and speed, as well as the possibility of static type checking.

Uber

Uber is one of the most well-known companies that use Golang. It’s used for the geofence service, which helps users find products based on their location. Geofence allows you to accurately define an area with certain constraints (for example, taking into consideration airports) and applies dynamic pricing.

Benefits Of Go Programming

The main benefits of moving towards Go programming are as follows-

  • Easy to learn
  • Faster execution
  • Cross-compiling
  • Active developer community
  • Comprehensive tool
  • Scalable
  • Garbage collection
  • Simplicity

Rust vs Go- A Detailed Comparison

Here is the detailed information on Rust vs Go-

Memory Management

For memory management, Rust uses a compile-time ownership model with zero-cost abstraction. If the Rust program isn’t memory-safe, it won’t pass the compilation step.

When it comes to Golang, though, it is totally automated during runtime. In simplest terms, programmers do not have to worry about the allocation and deallocation of memory during program development.

Performance

Both Rust and Go are known for great performance. They not only perform well but perform better than many of those languages that came before them. However, in terms of the Rust vs. Go Performance comparison, Rust is faster than Go in a variety of tasks. Overall, Rust is faster than the Go language.

Features 

Rust’s has a very large list of features, such as error messages, zero-cost abstraction, data race prevention, move semantics, pattern matching, and so on. The key features of Go programming like binaries and package management leaves far behind in the Race of Rust vs Go- features. 

Concurrency

These days, most applications are networked and distributed. So, we can say that the languages that work around these problems are lagging far behind. Developers should be able to complete tasks independently and communicate task status to one another without the risk of data manipulation.

Rust received the native syntax in the form of async/await recently, whereas that concurrency has been included in Golang’s syntax from the beginning. However, while Rust’s concurrency was a negative aspect of the language, it offers more memory stability.

Ease of Development And Learning

The readability of Go makes it simple to learn, and that’s why coding in Go is very easy. In contrast, the advanced concepts of Rust programming,  such as borrowing and ownership make the language more difficult to get. Rust has a very high learning curve. So, in the race of Rust vs Go- Easy of development, Go is the clear winner.

Maintenance

Everything you need to do to ensure your application is working effectively and will continue to do so is included in maintenance. The maintenance of the application in Go will be easier since the Go language syntax is very simple.

Community

The support communities of open-source languages are usually very large. Developer communities play an important role in assisting beginners to a language in learning about its applications and features and how to effectively utilize them. The community of Rust is stronger than the Go(Golang) community. So, Rust is the winner in the comparison of Rust vs Go-community support.

Security

Rust places a strong priority on avoiding memory-related security flaws. Therefore, programmers must go out of their way to execute activities that would be simpler in other languages, such as Go.  Accessing memory in an unsafe or inappropriate manner is one of the most common causes of bugs and security vulnerabilities.

Go is also not insecure. Rust happens to be the memory-safety king. To help prevent common memory safety issues, Rust provides multiple concurrent paradigms.

Popularity

We can look at the google search trends graph comparing the searches of both terms in the last 5 years to have an idea about which among Rust and Go wins the Rust vs Go-popularity race. From the graph below, Go was popular initially, but in recent years, the Rust language got more popular. So, we do not have a clear winner in terms of popularity. This is a tie round.
