Rust and Go stand out among the latest in programming from a wide range of programming languages. Even with that, the two languages share clear-cut differences and, at some point, perform related roles. Go, even though a new language, came slightly earlier than its counterpart, Rust. The former was launched in 2009, and the latter was launched six years later. With that in mind, Go has increased in popularity as it has served the programming space for years. However, Rust is a recent language evolving quickly, hence its increasing popularity and programming community.
In this piece, we will intensively explore each language to understand what can set them apart or even their typical roles. In our in-depth discussions about this duo, you will understand that both of the languages are somewhat better than the other. The point is that both languages are good enough but are just best in some situations. Therefore, there are instances where Rust is better than Go and vice versa. Let’s first dive into the similarities and differences between these two languages.
What Differentiates Go and Rust?
There is a clear-cut difference between the two languages on memory management. With both languages emphasizing memory efficiency, it is easier to note that both have different approaches to attaining memory efficiency. For instance, Go uses a Garbage collector to ensure memory efficiency. Still, Rust stretches further using the ownership and borrowing model and the Resource Acquisition Initialization (RAII) approach.
Simplicity and complexity
There is excellent simplicity when using Go. Moreover, the stability of the language increases with the release of its newer versions thanks to the development teams. A few simple but essential features are added to the programming language annually, thus its simplicity.
On the other hand, Rust is relatively complex due to increased inclusion and implementation of new features yearly. With frequent and more addition of features, there is a significant implication of rapid evolution in the language. Frequent updates also come with a disruption in the language’s development process. Thus, it means that Rust learners have to replace, refresh, or renew their knowledge with some updated implementations.
On matters of performance, both Rust and Go have commendable performance. However, Rust incorporates zero-cost abstraction features that support developing swift and better-performing programs. On the other hand, Go doesn’t provide such a feature or even a related one – it tries to ensure sufficient performance that allows programmers to write programs easily and quickly without worrying about speed.
With programming languages comes a greater need for concurrency, and Go ensures it’s a greater area of focus. Go tries to ensure efficiency and simplicity, which is supported through Goroutines. On the other hand, Rust supports concurrency, which runs through the support of the Async/Await paradigm and threading. Efficiency concurrency is quickly and achieved in the Go language compared to Rust. In Go, functions are asynchronous co-routines.
Compiler time speed
Rust runs compiler checks more often. With the consistent compiler checks, it is thus arguably true to note that it takes much longer to develop running software with Rust. On the other hand, Go has an extraordinary approach to faster development of initial software prototypes as it doesn’t run consistent compiler checks. However, the debugging and testing phases will always be cumbersome when using Go. Rust needs more development time with fewer worries on deployment as you cannot easily pass the compilation stage with bugs.
The learning curve
The learning curve for the two languages differs based on the features and functionalities incorporated within the language. It is easier to achieve high productivity with Go compared to Rust. With Go as well, programmers can achieve productivity in less time. With Rust comes the challenge of understanding some key concepts, such as the memory safety rules and type checks. Thus, compared to Go, Rust is generally challenging and complex and has a complex learning curve.
Rust and Go Use Cases
Go use cases
Go is a super language on matters of concurrency, thus making it a perfect fit for cloud computing. Cloud computing will always require excellent concurrency for migration or deployment. Therefore, Go meets concurrency needs related to cloud solutions and scalability in various applications.
Command-line interface (CLI)
Developing Command-Line Interface applications is much faster and easier with Go. It comes with several tools and resources, such as Viper and Cobra, which fasten the process of developing such applications.
Web app development
One of the most significant capabilities incorporated in Go includes easier and faster integration with modern development tools that enable the building of highly scalable web applications. With Go, developers can always enjoy speedier deployment.
Rust use cases
Rust is your go-to option if you need an excellent choice for developing drivers, file systems, and operating systems. It comes with more significant support for developing all-round and efficient software. Some of the typical use cases of Rust include:
Like Go, Rust is also an excellent option for web development services. With Rust, developers can easily enhance the reliability and performance of any web-based software, especially on the server side. Rust has resourceful features that make web development services much easier and faster. For instance, its resourceful features ensure it meets most of the project requirements and the current technology stacks. It is a go-for option when web development requires extensive focus on memory safety, concurrency, and overall performance.
IoT and Edge computing
Rust has a significant computational power. With the support for immense computational power, it is thus a perfect fit for application development and edge computing. With Rust, it is also possible to ensure fast data processing.
It is essential to understand the need to narrow down to specific project requirements even when working with Rust as a powerful language to support IoT and edge computing. Doing so will help you identify the usable Rust features supporting a particular project. Some key things to consider are the tooling, the current development ecosystem, and critical project requirements.
Microcontroller- and RTOS-based embedded systems
When developing microcontrollers and RTOS-embedded systems, it is always essential to consider Rust a perfect option. Rust supports high-level programming concepts and memory safety, which is an ideal choice for embedded systems. Rust also supports easier embedding during development through its resourceful package management solutions. The unique features embedded into the language will help handle microcontroller- and RTOS-based embedded systems thanks to its balance of performance, safety, and low-level control.
The tussle between Rust and Go about which language is better is common among most developers. It presents a nuanced choice, directing them to the critical requirements and needs of the projects they handle. Therefore, any project’s specific needs and priorities establish what language suits or fits what they want. From a general perspective, therefore, Rust and Go are both helpful, but their resourcefulness heavily relies on the project needs at hand. Developers should, therefore, assess the project’s needs before determining the duo and choosing the best for handling the task at hand. Rust has a greater focus on memory safety with more robust options, and these features can suitably fit a specific project. On the other hand, Go ensures simplicity and productivity, among others – all such features also suit the efficient development of specific software and applications.
