Golang vs Rust: In-Depth Analysis
Performance
Both Go and Rust hold their performance measures as prized possessions. As relatively new languages in comparison to something like JavaScript, it’s pertinent that they not only perform well but better than the languages that came before them.
A simple benchmark test proves that Rust is faster than Go in a multitude of tasks, especially those that are CPU-intensive.
This is likely due to its fine-grained control over system resources and zero-cost abstractions, meaning that high-level Rust code runs as efficiently as low-level code without performance trade-offs.
Rust also doesn’t rely on garbage collection, which can lead to issues with runtime pauses in Go. Instead, Rust’s ownership model ensures memory is efficiently allocated and freed at compile time. This allows Rust to rival C and C++ in terms of execution speed.
All of this makes Rust the better option for performance-intensive applications like cryptography, game engines, and even real-time systems.
On the other hand, Go is efficient and scalable. Even though garbage collection – which is great for memory management – can introduce latency, Go is better than Rust for networked applications and cloud-based systems, provided that you optimize for runtime.
While it does not provide the same low-level control as Rust, it compensates with an efficient garbage collector that automatically manages memory. Garbage collection ensures that memory is allocated dynamically in managed heaps, reducing the likelihood of memory leaks and improving usability.
Despite this, garbage collection introduces occasional pauses, which can affect latency-sensitive applications.
TL;DR: Where speed and performance are concerned, Rust outperforms Go. However, Go is still a strong choice for networked services and cloud-based applications.
Concurrency
Concurrency is a well-known feature of both Rust and Go, but they approach it differently.
Go’s goroutines – part of its built-in concurrency model – make concurrent programming simple and lightweight, allowing millions of concurrent operations. Unlike traditional operating system threads, goroutines are cheap to create and manage, making Go a great choice for applications that require highly concurrent execution.
Channels provide a safe and structured way to communicate between goroutines, further enhancing Go’s concurrency model. This makes Go particularly well-suited for web services, cloud applications, and backend systems where scalability and concurrency are essential.
Rust takes a safety-first approach, preventing data races at compile time using ownership and borrowing rules. Its async/await model, combined with frameworks like Tokio, offers powerful concurrency while maintaining strict memory safety.
Rust does not rely on garbage collection to manage memory, so it prevents data races and concurrency issues at compile time. The ownership and borrowing system ensures that multiple threads do not access the same data in an unsafe way, eliminating many common concurrency-related bugs.
While more complex than Go’s model, this prevents many concurrency-related bugs, making Rust well-suited for mission-critical systems.
TL;DR: Go makes concurrency easy and scalable, perfect for web services. Rust offers safer, more reliable concurrency for high-performance applications.
Memory Management
Go uses garbage collection to automate memory management. This simplifies development by removing the burden of manual memory management and reducing memory leaks and segmentation faults.
The issue with this is that it introduces potential latency. While Go’s GC is highly optimized, it is not ideal for low-latency real-time applications.
Rust eliminates the need for garbage collection by using an ownership model that manages memory at compile time. Every value in Rust has a unique owner, and when the owner goes out of scope, the value is automatically deallocated. Rust’s borrow checker ensures that memory is used safely and efficiently.
This prevents memory leaks, segmentation faults, and data races while maintaining high performance. Rust’s strict memory safety rules make it well-suited for systems programming, embedded devices, and high-performance applications.
TL;DR: Go’s garbage collection simplifies development but adds runtime overhead. Rust’s ownership model ensures memory safety without GC, making it better for performance-critical applications.
Developer Experience
Open-source languages tend to have strong communities of support behind them. Developer communities play a big part in helping newcomers to a language become familiar with its features and how to use it best.
Naturally, measuring the support of a community is not very objective, but Rust is still the more popular of the two.
Beyond that, Go is praised for being very simple and easy to learn, with a minimalistic syntax, fast compilation times, and even built-in tooling to do things like generate documentation and automate formatting.
Go is also statically typed, meaning better error detection, fewer runtime issues, and better developer satisfaction.
Rust, on the other hand, has a very steep learning curve thanks to its ownership and boring system, which can be difficult to grasp. Some say this is offset by the great documentation and developer tooling available. There are also many resources out there, like ‘The Rust Book,‘ which can help developers learn.
Despite its complexity, Rust results in safer, more reliable, and maintainable code in the long run.
When interviewing our developers here at Trio, they much preferred using Go. They love its simplicity and the fact that solutions are often straightforward. One developer also commended that the language seems designed to guide you toward a solution while making you think about nil values and error handling!
TL;DR: Without a doubt, both Rust and Go have strong communities, but Rust’s community gets the most visibility. Go is easier to learn and use, making it ideal for fast development and maintainability. Rust is more complex but offers greater control and long-term stability.
