In less than a decade, two new programming languages have emerged as major options for enterprise development: Go, created by Google, and Rust, developed by Mozilla. Both of these languages offer indispensable features for modern software development: a sophisticated and integrated toolchain, memory safety, an open-source development model, and strong user communities.
However, beyond these similarities, Rust and Go are profoundly different. They were designed to address different needs, solve different problems, and write different types of programs. Therefore, comparing Rust and Go is not about finding the “objectively better” language but rather choosing the language best suited for a specific programming task. In this guide, we will examine the key differences between Rust and Go and the types of work each of them is most suitable for.
Performance of Rust vs. Go
Among Rust’s major advantages, performance stands out as one of the most evident strengths. Rust programs are designed to run at speeds comparable to C and C++, thanks to Rust’s zero-cost runtime abstractions for memory management and processing. While it’s possible to write a slow Rust program, you can do so with the confidence that Rust does not sacrifice performance for safety or convenience. What Rust demands is an effort from the developer to learn and master the language’s abstractions for memory management.
On the other hand, Go trades some runtime speed for developer convenience. Memory management is handled by the Go runtime, which introduces some inevitable overhead. However, for many scenarios, this trade-off is negligible. Go is, by default, significantly faster than other convenience languages like Python, albeit at the cost of requiring strong types for all objects. While Rust is faster overall, Go excels in cases where performance is an absolute requirement.
Memory Management in Rust vs. Go
Memory management in Rust and Go is closely related to the performance behaviors in both languages. Rust employs compile-time ownership strategies for memory management through zero-cost abstractions. This means that the vast majority of memory management issues can be detected before a Rust program ever goes live. If a Rust program isn’t memory-safe, it won’t compile.
Conversely, Go is memory-safe because memory management is automatically handled at runtime. Programmers can write thousands of lines of Go code without ever having to think about memory allocation or deallocation. While programmers do have some control over the garbage collector at runtime, it introduces some restrictions. You can also perform some manual memory management in Go, but the language discourages this practice.
Development Speed in Rust vs. Go
Sometimes, development speed is more critical than program speed. Go offers both simplicity and speed. Its straightforward and simple features facilitate a speedy development process. Compile times are short, and the Go runtime is faster than Python (and other interpreted, developer-friendly languages) by orders of magnitude.
On the other hand, Rust has more language features than Go, which makes it longer to learn and master. Rust’s compile times tend to be longer than equivalent Go programs, especially for applications with large dependency trees. However, if a fast development cycle and quickly onboarding new team members are top priorities, Go is the better choice. In either case, if you have a team that is already deeply experienced with one of the two languages, lean towards that language.
Concurrency and Parallelism in Rust vs. Go
Modern hardware is multi-core, and modern applications are networked and distributed. Languages that don’t plan for these realities are behind the curve. Programmers need to be able to run tasks independently, whether on a single thread or multiple threads, and to share state between tasks without risking data corruption. Rust and Go both provide ways to achieve this.
Concurrency was a fundamental part of the Go language’s syntax from the beginning, through goroutines (lightweight threads) and channels (communication mechanisms for goroutines). These primitives make it easy to write applications that must handle many tasks concurrently without risking common issues like race conditions.
Rust introduced native concurrency syntax with version 1.39.0 in late 2019. While Rust’s concurrency lacks the years of consolidated developer experience behind Go’s concurrency, it inherits the advantage of Rust’s memory safety, meaning that Rust code that could expose race conditions simply won’t compile.
Interoperability with Legacy Code in Rust vs. Go
New languages like Rust and Go aim for memory safety and programmer convenience in ways that earlier languages didn’t envision. However, the new must always coexist to some degree with the old. To that end, both Rust and Go offer interoperability with legacy C code, although with different restrictions.
Rust can communicate directly with C libraries using the extern keyword and the libc “crate” (Rust’s term for a package). However, all calls to such libraries must be marked as unsafe. In other words, Rust cannot guarantee memory or thread safety for these calls.
Go provides the cgo package for working with C. It allows you to call into C libraries, use C header files in your Go code, and convert common data types between C and Go (e.g., strings). However, because Go is memory-managed and garbage-collected, you must ensure that any pointers passed to C are handled correctly.
In summary, Rust is slightly more friendly regarding C interop than Go, so anything with significant dependencies on existing C code may lean towards Rust. In both Rust and Go, though, interoperability with C comes at some cost to the developer: increased conceptual overhead, slower compile times, more complex tooling, and harder debugging.
Performance
Both Go and Rust hold their performance capabilities in high regard. Being relatively new languages, it’s crucial that they not only perform well but outperform languages that preceded them. Although both languages appear faster than others with their feature sets, the primary question is how they perform against each other? Well, a simple benchmark test demonstrates that Rust outperforms Go in a multitude of tasks.
In summary, when it comes to speed and performance, Rust outshines Go.
Features
Key features of Go, such as binaries and package management, pale in comparison to Rust’s extensive list of features: zero-cost abstraction, error messages, move semantics, data race prevention, pattern matching, and more.
In short, the Golang vs. Rust comparison highlights that Rust is more feature-rich than Go. Rust takes the win.
Ease and Speed of Development
Go’s readability makes it easy to learn, and consequently, coding should be relatively straightforward. In contrast, Rust introduces sophisticated concepts like borrowing and ownership, making the language more challenging to grasp. Rust has a steep learning curve and doesn’t shy away from admitting it.
To sum it up, Go is easier to learn and use compared to Rust. Go wins.
Maintenance
Maintenance encompasses everything necessary to ensure your programs run correctly and continue to do so. In short, maintaining your codebase will be easier with Go than with Rust because Go’s code is simply more straightforward.
In brief, Go will be easier to maintain than Rust. Due to Rust’s complexity, Go takes the win.
Community
Open-source languages often have strong support communities. Developer communities play a significant role in helping newcomers to a language become acquainted with its features and how to use them effectively.
Naturally, measuring the support of a community is subjective. However, many bloggers consistently praise Rust’s robust community, which is a good indicator of its strength.
In summary, without a doubt, both Rust and Go have strong communities, but Rust’s community garners more visibility in this Golang vs. Rust showdown. In other words, Rust wins.
Popularity
It’s challenging to gauge the popularity of languages as young as Go and Rust. Despite all the features and advantages you’ve glimpsed, neither Rust nor Go can rival the popularity of classic languages like JavaScript, Python, or Java.
Less than 10% of developers use either Rust or Go. Still, Go ranks 14th in popularity, and Rust lags behind at 26th, according to the TIOBE Index for January 2021. This index considers various factors in determining popularity, such as popular search engines, computer science courses, and input from skilled engineers.
Conclusion: Choosing Between Rust and Go
Choosing between Rust and Go for a software development project mainly revolves around selecting the language that possesses the qualities you need most for that project. For Rust and Go, you can summarize these qualities as follows:
Advantages of Rust:
- Runtime correctness (common mistakes simply don’t compile)
- Top-tier execution speed
- Memory safety without garbage collection (or with optional, experimental garbage collection via third-party projects)
- Hardware-level code
Advantages of Go:
- Fast development cycles
- High-tier execution speed
- Memory safety through garbage collection (with optional manual memory management)
- Developer convenience
- Straightforward code
Ultimately, the choice will depend on the specific requirements of the project and the priority you place on performance, memory safety, rapid development, or developer convenience. Both languages have their strengths and can be an excellent choice depending on the circumstances.
